If you've purchased anything online through Nashbar anytime in the past year or so, you should check your credit card statement carefully. They had a security breach and 150,000 credit card numbers were compromised. The breach happened last December and they didn't catch it until May.
We noticed a handful of mysterious charges dating back a few months on our card. Since the amounts were small, we didn't notice them for a couple months. We have since canceled our card. Not cool.
