> Buying 3 new-in-box $1000 cameras and returning 2 of them covered with your smudgy fingerprints is abuse

I agree. What percentage of online returns do you think is similar to this scenario?

What percentage of "buy N and return N-1" return patterns (which you believe to be abusive) is people buying multiple $1,000+ pieces of electronics equipment, versus say 3 sizes of shoes or 3 colors of a dress?

My guess is the former case, which I agree is abusive, is <1% of such return patterns. Partially because it's a legitimately stupid way to shop for those types of items and requires significant credit, while buying multiple sizes/colors of items like clothing is a completely sensible way to shop.
