Honestly I have ordered from them and been to brick and mortar stores and never recieved poor service.
My comment was more about the difference in pricing between PSA online vs in-store; I should have been clearer. PSA operates like two entirely different entities especially when it comes to ammo pricing. It makes no sense that you can buy on-line at a price (and sometimes even get free shipping) but go in their store and the same product costs sometimes $2.00 or more a box.
As far as CS goes, consider yourself lucky. There's plenty of stories we can share otherwise.
