Chat/call support. If you let them know they sent the wrong item and explain how it was on sale they should be able to send you the correct item without costing more.

Daddy Bezos is pretty merciful when it comes to customer support.

This literally happened to me 3 times for this card when it was on sale for $240. I should have called support rather than just returning and reordering. Literally got sent 3 3050's and not one 6650xt before I gave up!
