How to Compare Amazon Prices Across Websites

3 min read

The single biggest pricing gap in online retail is between Amazon and the long tail of independent stores selling the same commodity products. The boutique Shopify fitness store charges $156. Amazon charges $59. Both items are identical - same factory, same SKU, different branding. The only thing standing between you and the savings is whether you check.

Scenario A: You are on Amazon, checking if it is cheaper elsewhere

Less common, but worth doing for specialty items. Quick check: search the brand and model on Google Shopping. If a competitor undercuts Amazon, it usually shows up there. The manufacturer's own website is also worth a look - direct-to-consumer prices sometimes beat Amazon's third-party sellers.

Scenario B: You are on another store, checking if Amazon is cheaper

This is the scenario that actually moves money. And it is the one most shoppers never bother with - they assume the price they see is the price.

Manual approach: find the brand and model number on the listing, search them on Amazon. The same item is often half the price.

Faster: install BetterPrice. It runs on every product page automatically. The moment it detects you are on a non-Amazon store, it checks Amazon for the same brand and model. If a cheaper match exists, a panel slides in showing the savings and a one-click link. Free, no account.

Where the gap is biggest

Fitness equipment. The worst markups in online retail. Generic dip stations, yoga mats, dumbbells, resistance bands - 2–3x markups are routine on specialty fitness sites.

Home and kitchen. Cookware, organizers, gadgets - heavily marked up by boutique storefronts.

Phone and laptop accessories. Generic cables, cases, chargers. Commodity products with wildly different prices across stores.

Health and wellness gadgets. Massage tools, posture aids, sleep gadgets - sold via influencer-driven Shopify stores at insane markups.

When NOT to switch

Cheaper is not always better. Skip the switch if the Amazon listing is from a sketchy third-party seller, if the original retailer offers a meaningfully better warranty or return policy, if you need it urgently and Amazon shipping is slower, or if you want to support a small brand. The goal is informed choice - and right now most shoppers do not even have the information to choose.

Frequently asked questions

Is Amazon always the cheapest?

For commodity products - fitness gear, kitchen items, generic electronics, cables and chargers - Amazon usually wins by a lot. The volume pricing destroys boutique markups. For specialty items, the answer varies. The only way to know is to check.

How do I check fast?

BetterPrice does it automatically. The moment you land on any product page outside Amazon, it tells you if the same item is cheaper on Amazon. No copy-pasting model numbers.

Should I always switch to Amazon?

No. Sometimes the original retailer offers better warranty, faster shipping, or you want to support a small business. The goal is to know your options - not to blindly buy the cheapest version.
