Notes:

The suggestion I’m countering has 2 sales at 4 buds, however one of them was too high and invalid because he left out a few items included in the sale. I was buyer for that sale and it sold with a Bill's, a Cold snap, a Sub Zero suit, AND a Pool Party, so that lowers his sale down to 3.7 buds I think.

So basically he just left out the Pool Party and the Sub zero suit, which lowers the sale by at least 4 keys.

Conclusion:

Sales at 3.6, 3.6, and 2.7 buds. Since there is another sale at 2.6 in the suggestion I’m countering I’m taking the final range as 2.7 - 3.6 buds.

The suggestion I’m countering has 1 sale at 2.6, 1 sale at around 3.7 (See notes) and one at 4. Since we are trying to find the most suiting price in pure, then I think these 3 pure sales are better than 1 non pure sale. (and the other suggestion supports this range) Also yes, I was either the buyer or seller in all of these sales.
