Dealer selling B stock doesn't tell customers

Can someone please define the term "B stock"? I thought it meant that the product had a blemish of some kind, but was fully operational or the item had been discontinued. Also if it was opened to look at by the store and customer.

"B stock can sometimes be worse than used. It can also mean that product may'd came out of the bad batch and than re-manufactured or repaired."
- Shouldn't this scenario be called "refurbished?"

thanks.

Thanks Zydo, you answered my question. But if a unit is returned as defective, then repaired by you or the factory for resale, is that B stock or refurbished?

Marakanetz...that's funny. Wish I had a LIKE button.

Zydo, Thanks for the detailed info. I've bought demos before and saved a great deal of $$. But "B-Stock" is such a nebulous term, the dealer should always declare it during the sale.
