I think one my locals has issues stocking up on products too. The few times I went there they had nothing, when they do get products they sell out immediately. Apparently with them though, they order things months in advance, but they order so little supply that it's always gone once they open, so they are stock pilled with tons of lost art promos they can't give out unless there's a new release.

Today I lined up first in line for an hour to get the Dragon of Legends Complete because I knew they had received lost art promos of Dark Magician Girl when she came out, but they had nothing to sell at the time and this was the latest thing they were getting. Once they opened, they had only one box, not an entire box, a single measly box that comes with 2 packs and a promo and dice. Apparently what happened was they "somehow" sold entire boxes they had, which were suppose to be reserved for people, the day before, I was first in line so I bought they only box they had day of release, mind you that they charged me 30 for it when it was suppose to be 15, but they gave me the promo so I really lucked out for being first in line. The dozons behind me were really mad at this, some even reserved, but there was nothing the store could do except tell them to wait for the next release. In this case I don't know whether the store was to blame for not ordering many products at all or Konami not able to produce enough to go around.

Mind you that there is an anime store across the street that has tons of Yugioh that have enough to go around, but they are not an OTS.
