Elder Thing
Not to sound snide or anything but my copy I bought in about November of 2014 is still holding together well for about two years. It seems to have been a very hit of miss thing with that early print run.
All three of my core books were preordered and therefore likely among the first batches of the first printing. All three are still in near-mint condition despite heavy use for two and a half years. The issues some have experienced are definitely the exception and not the rule as far as I can tell.
It's still some serious crap if WotC is making people pay international shipping for the return though. I live in the U.S. so it would be an issue for me, and neither I nor anybody I knew had to return their books, but that is a lousy customer service policy if it's true.
