True, most bids can come in the dying minutes even seconds of an auction, so you would need to watch to the end, and still may receive that last second bidder winner.
You can let the auction run, and cancel the sale at the end, but this is very bad selling, and eBay do not condone it, and will place penalties on your account for doing this.
Be aware, if the buyer disagrees with your reason for cancelling , they can leave you negative feedback, eBay charge you a seller fee, and place a damaging defect on your account.
It doesn't take too many defects to close your selling account down permanently. eBay don't like disappointing their buyers, they tend not to come back to their site.
