Folks have probably been taking advantage of the RMA system and EVGA is now covering their own a$s.
To put it into a very plausible example for people to understand:
1) Customer puts in a request for Advanced RMA and allows EVGA to charge them the normal EVGA retail price (we'll say it's $1000).
2) EVGA sends out a replacement card with a $1000 hold on a payment method and customer now has 30 days to return "bad" card to get the credit hold refunded.
3) Customer gets replacement card.
4) Customer flips replacement card for scalper price (we'll say $1800).
5) Customer never sends in "bad" card for RMA and keeps their "bad" card that isn't really bad and keeps using it.
6) Customer gets charged $1000 from EVGA for not sending in "bad" card.
Profit: Customer is $800 richer for selling the replacement GPU for $1800 and only getting charged $1000 from EVGA.
This should be verified by the writers and added to the article. Pretty sure this is the case and wouldn't make EVGA look like the bad guy here.
