I tried to buy a 6800xt from the AMD website directly and at the last step of checkout it tells me I have "made an illegal choice and need to contact site administrator". I can't seem to find any real way of doing that so here i am having no idea what i did wrong.
Went to AMD Store and clicked on RX6800XT "Check AMD.com for Availability". It shows it is out of stock which is probably why you got that error message: https://www.amd.com/en/where-to-buy/radeon-rx-6000-series-graphics
NOTE: I believe AMD Forums should increase the size of Photos that can be uploaded from 3.07 Megabytes to 4 or 4.5 Megabytes.
it also doesn't matter what i have in my cart. i just tried buying a cpu that is in stock and i still get the same message
uBlockOrigin? or similar?
what about clearing cache and cookies in browser`?
