Conclusion: Current offers beat the low price by quite a lot. We see in link 4 and 7 that someone offered 2 buds + bills, which is around 2.3 buds. I'll give it a conservative bump up to 2.2 buds for the low price. Link 7's BO is 2.5 buds pure, and the trade is only three days old. Link 6 shows a very recent sale for a price higher than current, and over the buyouy price of link 7. Link 1 also commented that he would take the max head + 13 keys, which is just about 2.5 buds for it. Thus, the high price stays the same for now, and if the two trades go through then we can adjust the price accordingly.
