I purchased this product on sale in early December and my package arrived quickly. Unfortunately, dermstore sent me a $38 elta MD sunscreen instead of the product I ordered and was charged for ($86 sale price). Dermstore policy is to require you to return the incorrect item before they will refund you or make it right. I mailed the return and dermstore decided to refund instead of sending the correct item at the sale price. Not happy.
