-b/o of 2.5 buds, insanely old trade

Sales: 1.3, 1.7, 1.8, 1.8, 1.8, 1.9, 2.1

1.7 may look a bit low but quite a few offers are around 1.7 and it's close enough really. 2.1 is from the sale and and an offer. This is kind of a reconfirmation; the median is still the same as original. Unusual overpay and original prices used.
