We are happy to accommodate local pickups in most cases where an item is heavy or bulky. We can usually resolve any issues quickly. We are committed your happiness! Once a case opened, our flexibility to help you is more limited.
Any product you return must be in the same condition in which you received it and in the original packaging. You may not, without our written authorization, disassemble or remove a cover fastened by screws or rivets. You may not, without our written authorization, have an item serviced or cleaned.
Or do these things yourself. We take pride in serving customers worldwide and have customers in over 50 countries. If this happens, let us know and we will give you a more precise quote. We understand if the duty imposed by your country makes certain items unaffordable.
