The low end may need to be bumped up seeing the number of decent offers this one has been getting.

Overpay has been factored in already.

2 buds - collecting offer

2 buds + gifted blizz buddy ~2.4

Blizz Barnstormer + 2 keys ~ 2

Sulphurous Cowl ~ ??? (He took this, and I assume that he got ripped pretty bad)

2 buds + 11 keys ~ 2.4

2 buds + s sapper ~ 2.2

You can see that there are many offers (including pure) that easily reach 2 pure.

Suggestions or comments are appreciated.
