If you have ordered brand name product, and we run out of stock or there is any problem with your order, we will contact you, and you will choose how to proceed. If you have ordered generic product and there is a problem or we sold out of the generics, we will upgrade to brand name product without any extra charges. For example, if you order generic diazepam and we are out of stock, we will charge you the lower price of diazepam but ship Roche Valium at no extra cost.
