A recent price adjustment fiddled around with all the bud prices. I believe it was along the lines of 2.6-3.5 when I put it through a few days ago, and while the upper range was high, it was still more accurate than the price it had before then. It most certainly wasn't based off BOs, I typically use that as an easy sign of an overpriced suggestion. Anyway...

This looks good to me.
