yep, in addition to good stores like novelkeys and cannonkeys, divinikey sells KBDfans products, who have very good kits within the 150-250 price range.

usually when reselling in-stock boards, you won’t get back what you paid, so you’ll have two things going against you already, and then if you decide to build it then that’s 3 potential things that would make it harder to resale.

if you can, try to get a refund or if you still want that particular keyboard then see if they can exchange it if possible.
