How to Save Money on Amazon

4 min read

Amazon is the default for online shopping in the US - which means it is also where most overspending happens, just by inertia. You see a price, you click buy, you move on. The tactics that actually move the savings number on Amazon are not complicated, but they require the right tools running in the background.

1. Check the price history before buying

Amazon prices move constantly. The number you see today may be 30% above the same listing's price three weeks ago. Without a price history tool, you have no idea whether you are catching it at a good moment.

Install Keepa. It overlays a price history chart directly on every Amazon product page. You see the 30-day, 90-day, and all-time low at a glance. If the current price is near the all-time high, wait. If it is near the all-time low, buy.

2. Verify Amazon is actually the cheapest source

Amazon is usually competitive on commodity products, but not always cheapest. For specialty items - fitness gear, niche audio, kitchen tools, and many smaller categories - boutique retailers occasionally beat Amazon. And in reverse: many Shopify stores sell the same products as Amazon for 2–3x the price, and shoppers buy without knowing.

Install BetterPrice. It runs on every product page across the web - Shopify stores, brand sites, boutiques - and tells you instantly if the same item is cheaper on Amazon. The reverse also matters: when you are on Amazon, you can be more confident the price is competitive if BetterPrice has not been flagging cheaper alternatives on other stores you visited.

3. Stack Amazon coupons when they exist

Amazon has a real coupon system - actual codes that clip to your account and apply at checkout. Many product pages show a green "Apply coupon" button you might miss. Always check before checking out. The savings are typically 5–20%.

4. Subscribe and Save math

For products you genuinely buy on a recurring schedule (household supplies, vitamins, pet food), Subscribe and Save offers 5–15% off when you have 5+ active subscriptions on the same delivery date. Group your subscriptions to the same date to hit the higher discount tier. Cancel anything you do not actually consume regularly - the discount is not worth a closet full of unused product.

5. Lightning Deals and Best Deals

The Amazon Deals page surfaces time-limited price drops. Most of them are mediocre, but occasionally there is a serious one. Check the deal page combined with Keepa\'s history - if the deal price is genuinely the lowest in 90 days, it is real. If the deal price is the same as last month\'s "regular" price, the deal is theater.

6. Avoid the small price traps

The "Buy Box" winner on a multi-seller listing is not always the cheapest seller. Click "Other sellers" to see the full list, especially for used or third-party fulfilled options. Same product, sometimes 20% cheaper from a different seller on the same listing.

The recommended Amazon setup

Two extensions cover almost everything: Keepa (Amazon price history) plus BetterPrice (cross-retailer comparison). Five minutes to install, then they run automatically forever. The Amazon Coupons section gets a quick visual check at checkout. That is the whole system.

What is the best extension for saving money on Amazon?
Keepa for price history (knowing if the current Amazon price is historically good), combined with BetterPrice for cross-retailer comparison (knowing if Amazon is actually the best option vs. somewhere else). Together they answer both questions.
Are Amazon coupons worth using?
Yes when they exist. The Amazon coupon system has real codes that genuinely apply at checkout. The savings are typically 5–20%. Use them on top of price comparison and history tools.
