i think a lot of buyers do not understand the best offer system,heaps wait until the last seconds to buy,like a auction and i have even had a couple that have paid more than the asking price!!.

the thing i don't like about best offer is the sellers that dont let you know if they will except your offer for hours or days later,it stops me from looking for another item so if sellers are not able to check there offers regulary its not a good idea to list that way and yes the other end of the stick is the stupid low offers that some buyers put in that re a waste of time
