Used baby items..

Olivia
Is it weird that I don't want to purchase any used baby items, especially clothing?? I'm a FTM so everything I've gotten has been purchased brand new. It's one thing to get hand me downs from a family member - I get that. But I just can't go out to like once upon a child and buy things that have already been worn. My MIL invited me to go to like a flea market type deal with a bunch of used baby stuff because my SIL is going I guess and I like don't know how to nicely say I don't want to go and that I don't want anything purchased from there...
