I had an extra SI microbag I sold on eBay, with the auction ending last night. Got up this morning and had a few things going on but was able to get to the post office and send it out. Went in to put in tracking and realized the buyer hadn't paid yet. D'oh! Doesn't have a lot of history so hoping he comes through with payment shortly. If not, at least it wasn't a big ticket item I F'ed up.
