I ordered a repair kit for a 1B1 toilet fill valve - $4.47 plus $8.95 postage and handling. The part that came was the wrong one. I called sales and they researched it and told me it was the wrong one. They gave me the correct part number and said that I could order it. I asked if I would have to pay the $8.95 postage again and the answer was yes. I would expect them to send me the proper part for free, as they sent me the wrong one in the first place. They lost a customer over $4.47!
