Buy it now is simply an opportunity for the first bidder to skip the bidding process, and buy immediately for a fixed price, but once bidding begins BIN is no longer available. You can't have someone buying it now, and a winning bidder at the same time.
If you don't want less than £3.50, why on earth did you start the bidding at 99p ?
N ow that bidding has started, you can't move the goal posts. You will either have to sell for the highest bid, or pull out and get bad feedback and a defect on your account. You will also still have to pay the selling fees.
