As bad as that looks, and being no fault of yours, I wouldn't expect to cover any of the replacement costs. At the most, maybe they should have you pay the difference to get you A-stock. Personally, this scares me away from getting anything other than A-stock.
ALL of my speakers are "B-stock" from the factory outlet (redundant, eh?). We live in a high humidity area (Louisiana gulf coast) and keep out house on the warm side during the summer (78F / 26C) and the recording chart I borrowed from work shows a range of 75-85% RH. I've had my system for 4 years now and there are no signs of blistering or separation.
Now then, with that said, when we came back to the house after Katrina and there was 6" of standing water in the living room and condensation dripping down the windows - on the inside! - items that looked like Ichigo's were in direct contact with water. Items of similar manufacture (vinyl covered MDF) not in water were OK.
