I would like to suggest that if a vendor has sold a product previously at another store it is stated in the description on the items page. I purchase from different stores and I almost purchased some items here from a vendor and realized just in time that I already owned the items I purchased. I double checked to make sure and yes I had already purchased those items at another store. Yes the product was sold by the very same vendor that is now selling the item here in the Renderosity store.  Thank you in advance if you decide to implement my suggestion.
