I think you can buy as many as you want - I bought three last year (one of each design) then kept my favorite and sold the other two on Ebay. I got just over $50 for each of them - they were really popular. I can't guarantee that they will sell like that again but if they sell out fast then chances are...
They came with a little pink ribbon key chain on the handle and some L.C. coupons inside. HTH
