I've had two owners recently complain to me about dealing with sideshow.
One said that sideshow just cut the profit margin for retailers by 10%, from like 40% to 30% I think, so now he won't order stock really and will just do specific ppl's preorders.
The other lcs said that their sideshow account was cancelled when one day sideshow told them they had a new minimum order of $10k per year in order to be an authorized dealer through sideshow. The lcs said "ok well we've already ordered like $6,000 or so this year" and sideshow said "nope, that doesn't count, you have to place $10k woth of orders now or you lose your account". It's a smaller lcs so... Account lost.
