I bought and paid for a used iMac from B&H, got an order confirmation, and even a shipping notice for the order, but they never sent it to me, and never notified me I wasn't going to have it. My money was refunded with no notice, and I had to contact them when I got home from a week's stay in the hospital, with work piled up, and discovered my machine wasn't there. When I tried contacting them, I spent over 4 hours on the phone with their support and sales, mostly on hold, getting bounced from department to department, with, in the end, their best "We're sorry" gesture being $85 off a new iMac that wouldn't ship for 2-4 weeks.
