I've purchased one at Borders. It's not in the supermarkets or drug stores around here, so it's hard to come by for me. I'm not a shopper and stay far away from the malls (unless I need Satsuma from the Body Shop), so I don't get it often. And then it's always, always in a bag and I can't flip through it to see if I like the patterns, which just irks me to no end.
I'm in SE Michigan/Ohio - USA.
They sell it at our local Hastings. I've picked it up a few times, but like someone mentioned eariler, I'd prefer to look through it before purchasing, and it's always in plastic. I did find one that someone had remove from it's packing, and was happy to be able to look through it, but I'd never do that myself.
