I don't know that it is for online purchases. My wife is buying clothes and shoes off Amazon lately and we are on our third return for one pair of shoes because their size guide online doesn't correspond to what they send us at all. That's a 200% return rate on a single item, and that's only if we get the correct one shipped to us this time. Non commodity items have turned into a major crapshoot online.

Online shopping has spoiled me for convenience compared to shopping in person though. What's happened is that I've just ended up not buying as many things because I was trained to expect convenance and then it was taken away

I buy on Amazon a lot and I don't think I return more than one or two things in a year, typically. Even buying shoes online (I usually use Zappos) I haven't returned that many.

Do you buy clothes or shoes? Ive never had to return toilet paper, but we got a pair of boots that were a different size from the listing when they arrived
