AI Price Comparison
Finding the best price on a product should not require 30 minutes of tab-hopping across Amazon, Best Buy, Walmart, and three other stores while mentally tracking whether the $189 version includes shipping. Fazm visits multiple stores simultaneously, reads live prices including all fees, and gives you a clear comparison - all from a single voice command on your Mac.
The Real Cost of Manual Price Comparison
A 2023 consumer behavior study found that the average online shopper visits 3-4 websites before making a purchase. For higher-value items (over $100), that number rises to 5-7 sites, and the comparison process takes 20-45 minutes. Most people stop checking before they find the best price because the process is simply too tedious to sustain. They leave money on the table because comparison shopping is not worth the time it costs.
Price comparison websites like Google Shopping or PriceGrabber seem like the solution, but they have a fundamental limitation: they use merchant data feeds that update on irregular schedules. A retailer might update their feed hourly, daily, or occasionally - meaning the price on an aggregator page could be meaningfully out of date. Flash sales that last six hours, in-cart price drops that apply at checkout, member-only pricing for Amazon Prime or Costco members, and bundle deals exclusive to a retailer's own site all get missed entirely by aggregators relying on stale feed data.
The only truly reliable way to find the current best price is to load the actual product page on each retailer's website and read the live price. That is exactly what you do manually when you tab-hop. Fazm automates that exact same process - visiting each site, loading the product page, and reading the current price - but does all of them in the time you would spend on just one.

How Fazm Compares Prices Step by Step
You name the product and optional stores
Tell Fazm what you are looking for. Be as specific as you want - exact model number, color, storage capacity - or more general if you are still deciding on specifics. Specify stores explicitly ('check Amazon and Best Buy') or let Fazm pick the most relevant retailers based on product category. Add budget constraints, feature requirements, or preferences for new vs. refurbished.
Fazm opens each store and searches
Fazm launches your browser and navigates to each store. It enters the search query, identifies the correct product listing (not a similar or related product), and loads the full product page. For products with multiple variants (colors, storage sizes, bundles), Fazm selects the specific configuration you requested.
Reads the complete price breakdown
Fazm does not just capture the headline price. It reads shipping cost and estimated delivery time, any Prime or membership discounts, bundle inclusions, seller identity (Amazon vs. third-party), return policy differences, and any visible coupon codes or in-cart price adjustments. For warehouse clubs, it notes whether an item requires membership.
Normalizes for a fair comparison
A $169 product with $15 shipping is actually $184. A $189 product with free Prime shipping is $189. A $195 product with a $20 coupon clipped on the page is really $175. Fazm accounts for all of this and presents the true effective price rather than the number that appears largest on the screen.
Presents the comparison and completes the purchase
Fazm tells you which store has the best deal and why, notes any significant differences in shipping time or return policy, and identifies the second-best option as a backup. Once you decide, tell Fazm which store to use and it navigates to checkout, applies any promo codes it found, and completes the purchase.
What Makes Fazm Different from Price Comparison Sites
Real-time prices, not stale data feeds
Comparison aggregators update from merchant data feeds on irregular schedules. Fazm loads the actual product page each time and reads the current price - the same one you would see if you visited manually right now.
Total cost, not sticker price
Fazm includes shipping, visible taxes, membership requirements, and any coupon codes it finds. The comparison you see reflects what you would actually pay at checkout, not the number the retailer wants you to notice first.
Works with any store, anywhere
From Amazon and Walmart to Costco, B&H Photo, Newegg, AliExpress, and any regional or specialty store with a website - if you can open it in your browser, Fazm can check its prices.
Goes beyond comparison to purchase
Traditional comparison tools show you prices and send you to the store yourself. Fazm can complete the entire purchase once you choose the winner - no back-navigation, no re-finding the product.
Real-World Price Comparison Examples
Buying an ergonomic office chair
You have a $350 budget and want lumbar support and a headrest. You tell Fazm: "Find the best ergonomic office chair under $350 with lumbar support and headrest - check Amazon, Autonomous, and IKEA."
Fazm opens three tabs. Amazon: ErgoChair Pro at $299 with free Prime shipping, headrest included, 4.4 stars. Autonomous: ErgoChair Pro at $349 but there is a 10% new customer code on the page bringing it to $314, plus $25 shipping for a total of $339. IKEA: MARKUS at $229 but no adjustable headrest, free ship-to-store only.
Fazm's summary: "Amazon has the best deal at $299 all-in with Prime. If you want the cheapest option and can skip the headrest, IKEA is $229. The Autonomous option ends up $40 more than Amazon after shipping." You say "go with Amazon" and Fazm navigates to checkout.
Finding the best deal on a specific laptop
You want a MacBook Air M3 in Space Gray, 16GB RAM, 512GB storage. The Apple Store price is $1,499. You tell Fazm: "Find the cheapest price on MacBook Air M3 16GB 512GB Space Gray - check Amazon, Best Buy, B&H Photo, and Costco. Note any education discounts or open-box options."
Fazm finds: Best Buy has it at $1,449 (sale), Amazon at $1,499 (no discount), B&H Photo at $1,449 with no sales tax for most states (effectively $1,449 to $1,520 depending on state), Costco at $1,449.99 for members. Fazm notes that B&H has the best effective price for buyers in high-sales-tax states since B&H charges no tax outside NY/NJ. It also finds that Best Buy's open-box Excellent condition has one unit at $1,189.
Frequently Asked Questions
How does Fazm compare prices differently from sites like Google Shopping?
Google Shopping uses merchant data feeds that update on irregular schedules - often hours or days old. Fazm visits the actual store website in real time and reads the current price directly from the product page. It catches flash sales, member-only pricing, in-cart discounts, and store-specific promotions that aggregators miss entirely.
Can I set a budget and let Fazm filter for me?
Yes. Include a budget in your request - 'Compare standing desks under $400' - and Fazm will filter results to products within that range. It also flags options that are close to your budget if you want to see them.
Does Fazm account for shipping costs in its comparisons?
Yes. Fazm reads the full price breakdown including shipping, any applicable membership requirements (Amazon Prime, Costco membership), and visible coupon codes or in-cart discounts. The comparison shows total effective cost, not just the listed price.
Can Fazm compare prices on international stores?
Fazm works with any website accessible in your browser, including AliExpress, Amazon.co.uk, Amazon.de, and regional stores. For international comparisons, it notes currency and any obvious shipping restrictions.
How many stores can Fazm check at once?
There is no hard limit. Three to six stores is typical for most requests. More stores takes proportionally longer (roughly two to three minutes per store), but Fazm handles all the navigation and reading without any effort from you.
Can Fazm find refurbished or open-box deals?
Yes. If you include 'check refurbished options' or 'open-box' in your request, Fazm will specifically look for certified refurbished listings on the manufacturer site, Amazon Renewed, Best Buy open-box, and similar sources, comparing them alongside new options.
