I'm glad you're so lucky; in the past 10 years I've made many returns solely due to product defects. Recently I had a door knob that wouldn't install and a printer that tripped the circuit breaker when it warmed up. Sometimes you can exchange but then you run the risk that the next item will be equally defective.

I live in an older house where parts arent always the same sizes as now. I learn to buy a couple of the nearest best guesses and return the less better.

Not a single thing was broken? I had particularly bad luck with Amazon this December and received four different items broken when I opened the box.

So far, no. The only one I was nervous about was a ceramic cat water fountain, but it arrived fine.

I have had discs from Netflix arrive unreadable/broken (yes, I still do the by-mail thing as I get consistent picture quality even on Saturday nights). I'm not sure if that counts as a store return though, as I just drop it in the mail and they send me a replacement.
