Ah, I was including all of the delivery-related fees, which seem to be spread across three or four separate charges. The "delivery fee" is often waived, since they make plenty of money on their other delivery-related fees.
In my experience, anything less than a 50% off coupon for DD or UE is not worth it. Their markup and delivery fees really add up.
I'm reporting the itemized delivery fee advertised by the services. I did no investigation at all, because I wasn't looking for delivery.
