Sales: 2.3, 2.5, 2.6, 2.6, 2.7, 2.7, 2.9, 3, 3.1, 3.2

I put 2.5 there just because of a sale. Originally I thought it was too low but looking at so many sales around 2.6-2.7 it looks fine now. Yet it is still possible to get above 3 buds for this and 3.2 is in the range from a sale. Overpay and original prices used.
