Honestly as stand any item sold under 10L should not be best selling due to the loss of views other merchants have on the MP, A lot of people base their RL income off the sells they make on MP along with in world, You hit best selling now and get a whole bunch of crappy freebie things and some sold out statue for 1million lindens... That is a big dent in the economy of SL... But in the end LL still makes their money so why would they care about the merchants (who by the way are the reason this game expands to new crowds the way it does)
