I can't even use this stupid gift card to buy supplies like album pages or 2x2s because they are listed under "coins".
The work around on this is to ask the Seller to list/move the item you are interested in to a gift card acceptable category. So, if you are looking for 2x2's, and they happen to be in "coins and currency", ask the Seller to move them into an "supplies" category and send you the new item number.
I've had sellers move stuff I've wanted (collectible coins) out of "Bullion" and back into "Coins and Currency" so I could earn eBay Bucks on a purchase. Most Sellers have been very accommodating about doing this. The most recent ones were some 2021 Morgan's listed in "Bullion" when in-fact they are actually collectible coins, denominated in dollars with no mention of purity or weight.
You just sometimes have to get creative.
As a last resort you can give the gift card away for a birthday or Christmas gift!
