It's not that pricing is unfavorable, he just will only shop at one vendor. That same 6800 XT Merc 319 is available at another retailer (Canada Computers) for $699 either at B&M stores or online with free shipping.Can't help it prices in your country are unfavorable.
Amazon just has pretty bad prices on RDNA2 GPUs relative to other retailers, so for him he's pretty limited. Everyone else can get a better deal if they so chose.
