One of our best sellers is a set of one dozen small cards you leave on peoples windshields that say three different phrases. 1) you suck at parking 2) next time you park please consider being less of a dick 3) you park like an asshole. They wholesale for $4.00 a pack and retail for $8.00 so this is a wonderful free gift & a perfect cash wrap product. I've also had several stores break up the packs & sell each card for $1.00!
