Product Mix / returns
In most cases, these are untested customer returns, usually packed in original boxes (that is not a rule though). Since there are various reasons for returning the products, some of them might be fully working ones, while the other might not. The basic thing is, that neither You, nor the wholesaler, know the condition of these items, therefore they are sold on as is basis, without a warranty, or even an option of returning them. On the other hand, products that have not been tested for working are usually sold for a small fracture of RRP, making them quite interesting wholesale products to buy.
