I've banned myself temporarily until I sell some of my own, then I'm only going to allow myself to shop with that paypal balance made from existing frags. I won't feel guilty then.
I keep going on ebay and watching loads of really expensive ones, and then just ignore the end of the auctions or only look when they are done. I've not bought any of the vintage Joys or the really expensive Sikkim and Houbigants. It's making me feel good to not-buy. (because I haven't put any for sale yet).
