For me, personally, it is what shipping fees have become. Especially purchasing from U.S. sellers and the use of the global shipping program.
I've cried about these fees before but they are seriously getting out of hand. $35-$50 dollars+, U.S., to ship one card that can cost a 1/3 of the shipping fee.
It's rare now, unless it is from a CDN seller, to find shipping less than $25-$30 dollars, which, of course, has really deterred me from looking at cards from many U.S. sellers.
But, all that aside, Merry Christmas everyone.
