I bring atleast one if not two full size suitcases full of just straight donations every trip. i do usually get opened but they ask where going and thank me. never have had to pay a fee and maybe that is luck but I have brought: meds,1st aid kits, womens supplies,baby supplies, lots of meds,lots of shoes, baby clothes,hundreds of balls, books,phones,tooth stuff. I just be honest every time and have never paid a fee and never not been thanked.
