Writing about a graphics card, a phone, a watch? Drop in a small box that shows the current cheapest one on eBay and keeps itself up to date. One line of code, no account, works on any site. Pick a product below and copy the snippet.
The box pulls live listings from eBay through our price service, filters out parts, fakes and broken units, and shows the genuine cheapest total price with a link to the listing. It refreshes every time your page loads, so the number is never stale. It is affiliate supported (eBay Partner Network), which is also what keeps it free.
Keep the small “price data by usefulHQ” credit link in the box. That is how people find the full tools, and it is the whole deal: you get a genuinely useful live widget, we get the credit. Style it to fit your site with the data-color attribute.
