opinions needed..

Sets

I am thinking of putting this my ebay descriptions, (I haven't done it yet, I have never cancelled an auction early before either)please answer poll. A) Is it illegial, b) would you bid c) please provide comments too as to if it would help or hurt me in the future.

"Bid Early, This piece is also on my trade list, I am an active on-line trader, If I receive a fair offer and there are no bids I will end this auction early"
