You can buy stock from the vendor and sell yourself on eBay or iOffer.
Many people will be interested in this product, because the box fits the Sony Reader perfectly and the price is reasonable. You can sell it for $8 or something, maybe even more.
Also the site is all Chinese and no-one likes to go through a middle man. Maybe I would be interested to sell them, if I got a good price for bulk purchase.
Does this box fit Sony PRS-500, 505 and 700??
