emm,
maybe. there is a huge BUT - if they try to accumulate expenses over 'free' shipping(which we, as customers have not been asked for), they have to go rising prices all over their items, and not specifically on B grade HO backs.
Even if i call , what do you think they will tell me? )) they will find dozens of reasons, to tell the customers on why they rise up the price of an item (one item for the moment)
