My local card shop used to not deal in non sports. I got him to start buying non sports like the Pop Century and other products. He found out that those products started flying off the shelf.
If I see something I want and I know way in advance, he makes his calls to his distributors and checks to see on availability ... Normally he can get a case of anything.
He asked for 3 WD Season 2 and got allocated 1 ... which he sold to me on release date for regular price.
He asked for 3 BBT Season 3&4 and was only allocated 1. I'm getting that too
And now I get calls from him asking if he should buy this or that regarding nonsports. Heh
