Bought the wrong ink cartridge

[Bobby68]

I RECENTLY BOUGHT HP INK FROM THE STORE
(Walmart) , I didn’t think anything of it all these ink numbers and stuff are kinda confusing. But my printer is telling me the ink isn’t compatible. I bought 910 , and need 902 . But now the store is saying I can’t return it because it’s already open so now I’m out of 65 dollars so I’m here wondering if there is anything you guys can do or have a solution.
