i'm having difficult decision's committing to which camcorder/dslr i should buy. is it possible to get a full refund excluding shipping cost, i want to buy 1 cam at a time test it for like 10 days and return and try the next, then buy the best that suits my needs. i see this as being illegal but not sure because if i were to buy a cam at a local store and return because i was not content with the quality of the camera. i could return and buy a different 1. so please tell me is this legal and dose amazon offer full refunds. plan to test panasonic tm900, canon rebel t3i, and Nikon d5100
