I don't wear acrylics, I don't bother with manicures....all up, a few bottles of nail polish will only cost me about $12 (I get them cheap but it's discontinued shades of Revlon and all that) and I do the lot myself. Not bad for me.
In regards to the OP,
Almost reminds me of a few customers I had today. We're phasing out plastic bags at the moment and are selling bags in packs of five. Good price and they're very strong. People keep returning THEM instead of returning the junk food that they buy.
