I tried to purchase an ONLINE order for the Second time using a gift card provided by Davidsons and they will not accept it. I called the store to see if they can use a gift card and the lady said to enter the information online. There is no place to enter it online, so we placed it in the special instructions. Shortly after we placed the order, we received a call stating that the gift card cannot be used. The website is flawed when using gift cards.
