I sell and ship stuff on Ebay, for myself and work. Work is mainly tail lights, ect (I work at a salvage yard). The price of shipping has gotten insane! Anything over 12x12x12, no matter the weight, is so expensive now. Especially for me in Michigan, going to the west coast or down to Florida. It has really hurt sales. A tail selling for $15, but add $20 to ship to California, makes no sense if the customer can buy it locally for like even $30-40 and not have to wait. (Plus the Ebay fees, which are a percentage based on the selling price AND shipping cost)
Even small stuff, the cheapest package of any kind other than envelopes, are $4.50 and up. I wish I could get the discounts big shippers like Summitt, ect must get, for them to be able to offer free shipping on stuff like wheels, and other bulky items!
