Becoming a preferred or authorized dealer with companies like EVGA and Nvida is often not just as simple as partnering LOL. It usually has ties to volume of min buys and quotas of product that need to be sold.
Mom and Pop shop want to be featured on a x brand vendors site, you have to purchase large sums of product from x vendor. If you don't have that kind of capital, you get it from a middle man or a distributor that EVGA or brand x sells to knowing full well where the cards are going to go and its usually part of a distribution strategy.
If the warranty isn't the same regardless of where I buy it from or where the retailer buys it from then that's shady business I don't care what brand it is. that being said I've never had issues with EVGA branded cards and the people I know who have always received top tier customer service from EVGA.
As for bitcoin mining, I have no idea what that is or why it's an issue. But don't you think running a running a promo for special set of vendors is only going to make the stock level problem worse? Consumers now have an added incentive to buy the card from retailer A over retailer B. I can tell you that I found the card I was looking for in stock (still is as well as of this posting) on Amazon when all the other authorized retailers (for that promo) were out of stock.
Obviously authorized retailer status is tied to quantity of product purchase, or they would just list everyone as authorized.
You don't seem to understand the warranty aspect. This isn't shady.. If you can't prove you purchased the card legitimately from an authorized retailer, then that is a fault of the retailer. They just had this come up recently where a user bought a card from an unauthorized dealer. The warranty is clearly laid out. EVGA offers a 3 year guest warranty. If you hold a card for 2 years, and then try to sell it, they third buyer gets 1 year. Period.
Buy directly from nvidia.. Their warranty states Original owner ONLY. So, that would mean there is no warranty at all from a mom and pop store that isn't authorized to sell them. If you want to be a retailer, you need to be able to understand all aspects, but it doesn't seem like you care yo even read the warranties that are laid out and available. They aren't shady. If they were hidden, it would be shady.
If you bought off Amazon US, you wouldn't get the game anyway. Too many people bought cards, received codes instantly, and cancelled their orders, so amazon stopped participating in game promo's. It would be good, if you are looking into buying a game strictly for a promo, to spend 5 minutes reading about this. If you dont know what mining is, you may want to use the oracle (that is google) to learn why there is a shortage.. i promise, shortages have nothing to do with a game promo.
