Love this app, stopped working, 7/4/25, can you update/fix it? Thanks!
Does not work
No longer working early 2025
No longer working. Please update.
Works for me. Appreciate the effort you put into this.
does what it says
Works for me; click the 'view price' link and it shows up.
I was really looking forward to using this tool. BUT IT DOES NOT WORK.
After my first review in April, it started working. And it was great. However, I'm sad to report that as of today, it no longer works... Get it together, guys! --- I don't know if I'm doing something wrong (perhaps I have too many tabs open, Idk) but the only thing that this displays when I use this is "Loading". Like someone else said in their review, I'll definitely change my review to 5-stars if it ever works because I love the concept. It's extremely frustrating because most of the other reviews say it works perfectly.
Does not work. So sad.
any idea why this wont work anymore?
Annnnnnddddd again it doesn't work. Come on!
not workin
Just downloaded and seems to be working like a dream!
great idea but DOES NOT WORK. Too Bad.
Does not work. Just sits in "loading".
Still doesn't work for me and I've tried multiple PCs.... Hopefully it gets fixed. If so, I'll gladly change this review to 5 stars
Works great! Thank you!
Works for me. Wish this was out years ago. You have to click a "view price" button and it takes a second to load. The font is also to small. I also wish it could show the price automatically so you don't have to click the button. Would pay for that feature honestly. Still great. Works for everything not just cards. Every eBay buyer should install this.
If you are claiming this worked as of Jan 1st, well it's broken again as of Jan 19th. I love the extension, hopefully you can fix it again. I can only assume ebay is changing something on their end of things that's causing it to break?
Doesn't work. downloaded, went onto ebay and filteredd by sold and it just still shows crossed off without new price
Finally, been looking off and on for a while for this and it works great. Hope you keep it up and going this is very helpful in deciding on pricing on some items. Thanks Again
Dope extension - does exactly what it says on the tin
It's great on first glance, but there's one thing to mention, and hoping that a fix can be somehow developed and added in. If the BIN price is in italics, that means it was purchased using a different currency. When it shows the crossed green price, it shows that price in USD, but if it was purchased in another currency, say CAD, the addon shows the actual purchase price in the foreign currency. Is there any way to add in something that notices if it's in italics and does the conversion? I get you extension devs put a lot of work into this stuff already and I appreciate the hell out of it, but it would be an amazing add!
Works in edge as well and exactly as described.
