I'm new and also looking forward to swapping. I don't wear perfume but have about 5/6 bottles at home from Christmas's and birthday etc (I'm forever telling family I don't like perfume). I'll bring them in to work tomorrow and stick them up, I can't remember the names but theres def a DKNY and a Dior one. Most of them only have a few squirts gone out of them from whenever my Mam or sisters stay over. Great idea!
