Red"It looks like the days of buying a card that is professionally graded, sight unseen, are almost over (if not completely over)."
If you're buying in this manner from a legit seller that you have complete confidence in then there's no issue because you'll be able to return a card you don't like that was purchased this way.
If you're buying this way from a scammer there's a good reason you won't get a good look at the cards before you buy them, and no chance you'll have any luck trying to return them.
The same goes for raw cards, PSA, SGC, stamps, coins, Rolexes, and Beanie babies.
