hahaha depends on what shipping company you used, and the type of service; overnight, 2nd day, 3rd day. It also depends ont he amount of insurance you requested. ALSO, if you did not package the material yourself, they charged you an arm and a leg for packaging(thats how they make the most money) Best to remember: Package your material at home, buy boxes at places like office depot etc, and request the CHEAPEST shipping; tell them you don t care how long it takes to get there. You will be ok!
15 in x 10 x 1? Do you mean 1 foot? Did they pack it for you? If so, in order to be insured for damage, the box would have to be at least 19 x 14 x 16, which is a decent sized box. (Size matters) Between the packaging costs, plus the shipping all the way across the country, it could cost that much. For future reference, avoid selling low value, fragile items, like a car amp as the packaging price plus shipping price will often erase your profit, particularly if it has been sold to someone on the other side of the continent.
