I am OK with mostly consumer-friendly return policies, but I wish that retailers would be more strict sometimes for those of us who buy returns. When I buy a bag, I keep all the packaging protection on when I do my quality inspection. Even then, if I am not 100% sure, I still keep it in all of the original packaging until I know that I won't return it. If I do return it, I have all of the original packaging as I received it and try my best to put everything back into the box for a return.
This is not always the case for returns, as this forum and some of the blatant YouTube videos show. I don't care that a bag is a return--I care if the bag was damaged by a person who decided not to keep it. These are often the same frequent shoppers who do not want "damaged returns" themselves, yet they fail to return items as they received them.
I know I got a very nasty stare the other day in a boutique which I shall not name (I just decided not to shop there anymore, full stop) because I asked if they had any of a particular item that HADN'T already been unpackaged. I ask because I don't want to bother with inspecting an item from top to bottom for potential flaws or makeup or nail polish that some other buyer put on.
I like that people show items here and online, but some of us avid collectors don't play nice. So retailers have to make these policies to keep their bottom line cushy. Given how many people don't play nice with goods they intend to return, 30 days from shipment and/or arrival is reasonable enough, in my opinion. Some people ruin things for the rest of us.
