I found these Sally Hansen Nail Polish Strip value packs at Walmart. They are only $12.97 (US dollars) - considering the regular price for one set is $8.50 you'll save 4 dollars getting a set of two!
I was happy to get the butterfly and lace designs to try. If anyone doesn't have access to these just let know and I'll pick them up to swap or just do it as a favor. International shipping is a possibility, too.
