-b/o of 3 buds, 1 month old

-highest offer of nnb juju+6 keys=~1.5 buds

-regular offers of nnb jujus (~1.2) rejected, too low

http://www.tf2outpost.com/trade/15181301

-b/o of 2 buds, 2 weeks old

-instantly rejected 1 bud, in original price but way too low now

Low end is from the 1.5 bud offer, it wasn't rejected for the value, seller didn't like the effect and has a very high b/o of 3 buds. High end is from 2 buds b/o up for 2 weeks which is not a short time and no offers apart from the sale even close to 2 buds, so I'm suggesting 1.5-2. Original price was 1-1.5 so this is quite a substantial increase. Unusual overpay and original prices used.
