I found this source by accident and to my surprise they have the cheapest slin pins I can find. It's hard finding a source that will ship pins to APO addresses. Only 8$ for 100 of the clever choice brand. And 4$ for 200 alcohol prep pad. So my total order was only 12$ with free shipping since it was the 4th of July. T/A was spot on, shipping was discreet, and I will be ordering my slin pins from here from now on.
