people miss spell all the time I really don't think it is going to effect the out come much at all -the only thing I see the miss spelling effecting is like in the search box-lets say someone wants to go to amazon , when they type amazon in the search all these links pop up for them to choose-ultimately amazon.com would be link # 1 then a bunch of linked amazon links will show(his auction wont show as a link option) because it is miss spelled it wont show up at all...so to enhance your visibility /chances of more bidders-DONT MISS SPELL-GET YOUR AUCTION SEEN....also I wouldn't list pricy auctions until you earn your sellers wings-people don't bid high with new sellers-items/auctions will not get the credits/bids that they deserve ...however gift cards are well wanted so maybe it will.
