Just make sure there are no gun markings on the outside of the box. Retailers will either put the original gun box in a larger cardboard box and pack it with foam, or flip the original box inside out and ship it that way. If you have a hard gun case, cover it up with some pink disney princess wrapping paper and ship it that way =P.
Thank you very much for the tips. Really apreciated.
