If u can see in item history, it was sold before bud price change

Tue, 17 Mar 2015 00:17:03 -0700

Buds changed its price like 3 hours later, thats why i counted bud as 11 keys.

Also exist 1 more open trade for this item, but with not set price:

but its not any proof.

Hope, i didnt make any mistake doing this suggestion, its my first and also sorry for my english, its not my native/first language.

Sorry for asking, but how it is possible that some suggestions are accepted like in few hours and mine is still not accepted/canceled after 8 days? Moreover some of sugestions need only like 50-60 votes and mine already have over 190????
