How to Track Electronics Prices on Amazon and eBay
Electronics price history: spot real deals on Amazon and eBay
You’re comparing a laptop, a GPU, or a TV. Amazon shows a lightning deal; eBay has “used — like new” at a price that looks too good. Without history, you can’t tell a genuine drop from a recycled promotion or an optimistic asking price.
This guide shows how to track electronics price history on Amazon and eBay in your browser with AuctionMate.
Why electronics prices move so fast
Electronics retail runs on dynamic pricing, stock waves, and campaign calendars (Prime Day, Black Friday, back-to-school, console launches). The same SKU can swing hard within days.
Common traps:
- Strikethrough “was” prices that don’t match the real recent range.
- Deal badges that look urgent but sit above last month’s actual floor — see Discount or manipulation? for how “discount” framing misleads.
- New vs used — Amazon retail/3P offers vs eBay private sellers; different contexts, same need for history.
- Shipping and fees — the headline price isn’t always the checkout price.
A single number on the product page is not enough. You need price history.

How to check electronics price history without a spreadsheet
You can screenshot prices and track them in a sheet. It falls apart the moment you follow five products across Amazon and eBay.
AuctionMate is a browser extension that overlays a 60-day price chart, a rise/fall signal, and optional price alerts on the product page. The chart feature is explained in Don’t buy blindly — here we focus on electronics shopping.
Steps:
- Install AuctionMate once.
- Open a product page on Amazon or eBay.
- Read the trend, then open the 60-day chart.
- Compare today’s price to recent lows before you buy.
- Set an alert if you’d rather wait for a drop.
When the chart actually saves money
- Deal events — “lowest price” banners that sit above last month’s real floor.
- GPU / console scarcity — see whether the spike is cooling or still climbing.
- Amazon offer hopping — same listing, shifting deal price; history beats a one-day screenshot.
- Used gear on eBay — check whether the asking price keeps sliding before you bid or message.
Buy electronics with data, not banners
A red “-30%” badge is marketing, not a strategy. On Amazon and eBay, AuctionMate puts price history where you already shop.
Install AuctionMate and check electronics price history before you hit buy.
