expansys b-stock?

B-Stock is B Stock no matter what company you buy from. It can range from faulty repaired returns or can be as simple as an incorrect order or cancellation. I've bought plenty of B Grade stuff over the years (not from Expansys) and have never had a single problem with any of it, but maybe I'm just lucky. General rule of thumb is to stick to well known reliable brands but even the big guns are well able to churn out the odd lemon. If the price is discounted heavily enough it's usually well worth it and to be honest I'd only buy B Grade if it is heavily discounted.
