I received a $115 charge on my Amex. I ordered a $50 of groceries (for what should've been $30 Max!) and there were $20 of charges (tax, delivery fee, tip). I called them to ask about the excess charge and after 30 min of run around, was told they don't see the order so they can't send me the receipt. I asked then how can you charge me anything for an order you don't have a record of? The man said he can offer me $5 for "appeasement." I asked to speak to a supervisor or someone who has the authority to research the records for the order and he said I can hang up and call back and hope to get another customer service rep. Basically, if you want to give them the ability to charge what they want without the opportunity to see your receipt or question charges, then go ahead and use them. Otherwise, buyer beware!
