I ordered 3 parts and got the order confirmation email, including the shipping charge of $8.95. However, what they delivered was 2 parts and they bumped the shipping to $15.95. Meaning I got only 2 of the 3 parts, and paid even a bit more in total (Paypal will let the transaction settle above original authorization price, up to +15%, and they won't even send out a notification).
I called the store after I received the fraudulent delivery, and they did not care, and hung up on me.

"The shipping cost might be recalculated if the the actual cost is slightly higher, but if the actual freight is substantially different from the amount calculated at checkout, you will be notified prior to shipping your order for approval of any additional freight charges exceeding $8.00 that may apply." Is the terms the customer agreed to at checkout.
