The original prices on the items page changes in the cart to cancel out any coupon you may have. For example, $5,000 original price with 10% off coupon. In the cart now you'll see, original price is $5,500 x 10 % discount = $4,995; NOT $5,000 x 10% discount = $4,500. I spoke with customer service at length about this, even spoke to a manager, they said that's how they run discounts. Just increase the original price to cancel out any provided discounts???!!! Aweful!
