I don't mind buying used bags on eBay. I see them as "pre-loved". I earn a pretty good salary but can't afford to splash out regularly on new bags.
I love browsing through people's auctions for great bargains. But as there are a lot of fakes out there, I make sure I do all my research and ask all the right questions before buying them.
I think I've gotten 2 speedys, a horizontal lockit, a cabas mezzo and some smaller pieces that way. So hey, I'm all for it!!
