Slightly higher prices - Infact I think they are overcharging for the bitcoins at the moment. Their buy prices are more then then the Mtgox exchange prices too. 
. And when you see their sell prices its around 3k less then MtGox .
Busellbitco.in derive their prices from averages of various exchanges and as we know apart from MtGox rest exchanges are on lower side so automatically their prices should certainly be lesser on site but its higher then Mtgox (buy side) and much lesser on sell side(Mtgox).
Another thing is that, over and above their price they do take 3% commission +96 as their transaction fees making more costlier to purchase and less attractive to sell.
