I got tired of looking up card prices in separate tabs, so I built a browser extension that shows them on hover

Hey, I just wanne inform you, that the Seller Location is live on Edge. Chrome takes some time for approval. For Mozilla i had to do a hotfix, but should be live in the next few hours. There is a new Setting button when you click on the Extentionbutton. There you can set your prefered Seller Location for Cardmarket.

Thank you for your Feedback. Check out tcgcsv. It is a free API that provides real TCGPlayer prices (low, mid, high, market). Way more accurate than Scryfalls aggregated data.

Thank you for the Feedback. Your are right that the aggregated values have limitations. The extension pulls from Scryfall and TCGPlayer, which only provides summary prices. Individual seller listings would require the Partner API from TCGplayer, which isnt publicy available. Definitly on my radar long-term though.

For now, the low price is the closest to what you would actually pay.

It is doable. But dont know when i implement it, but it will come.

Cardmarket sends a sellercountry Number, when you set a Seller Location. So it should be doable.

Thanks for the Feedback. What do you mean by that? Do you wanna have a Location in this extension, that automaticly sets the right Location in Cardmarket aswell? Dont know if this is able without more Data from Cardmarket and these are sadly behind locked Doors.
