Nice surprise at the bottom of the box

I recently got my hands on an auction of 40 towers, big copiers, monitors, keyboards etc... Paid $130

Long story short I was kind of bummed that the towers were missing most of there ram and hdd's. Might still squeak out doubling my money if I was lucky. I grabbed a few mystery boxes as well figuring they had mostly junk in them. Well that was the case, but at the bottom of the last box was 12 unopened HP inkjet cartridges, and a few opened but unused! Retail value is around $200-$300 for all of them. Doubt I will get that much but hey, now I 3x or 4x'd my investment. I went to bed a happy guy!
