I would look at the page that is selling the RX6xxxx GPU card to see if it mentions the AMD Promotion.
Went to Amazon for the MSI RX6600 XT and it does mention the AMD Promotion. This is a link that shows all the AMD GPU cards that qualify for that AMD Promotion: https://www.amazon.com/promotion/psp/A1U3HEQI0GF1GF?ref=psp_external&redirectAsin=B09BK8NCPB&redirec...
NOTE: To qualify the GPU Card MUST BE SOLD AND SHIPPED BY AMAZON. Another words it can't come from a 3rd party seller at Amazon.
