I would give Amazon prime a 5 star rating except their billing is so frustrating. For example I could order 3 items in one purchase and the total amount out of my checking account will be multiple purchases and usually doesn't total up to the same purchase amount. It makes it extremely difficult to figure out if I'm being charged the correct amount. When I tried to resolve this on amazon help chat I was told it could be because the purchase had multiple shipments. This is a ridiculous reason. If your purchase total is $75 then your checking account deduction should show $75. Not multiple deductions that don't equal the exact amount of your order. The amazon chat help was not helpful at all!
