Anybody can have a bad day, but Hill had several in a row with me! I ordered a new firewall, which I paid shipping on, and it came with obvious damage from the factory. I complained and they quickly shipped me another, shipping prepaid. I shipped the damaged one back at my expense (it was more convenient at the time, for some reason) and was promised a reimbursement for shipping charges to my account. It slipped my mind, and by the time I remembered to check it was past 30 days, and I hadn't received the reimbursement. I was then told It was too late to receive a reimbursement, but I would receive shipping credit on my next order!
About that time I found Spectrum Aviation, where I got a bigger discount and free shipping (this was BEFORE I negotiated). I asked Hill to give me a similar deal, and was given a rediculous statement about how much HILL already loses on every sale! I haven't done business with Hill since, and I doubt that I'll ever see the shipping credit. Whomever offers the better deal is who I'll do business with, and that can change on a daily basis. Shop around! It pays!
