I am going to book a 3* hotel near OKC airport for May 5 through 10-5 nights. I currently could book with Expedia for a $285 total less a $50 credit I have for a total of $235. Expedia's hot Wire driven price is $49 for the 3*. I've never bid before so I would like to know if I would possibly get a lower price by bidding on Priceline and what might be the amount I should bid. Also is it better to wait until it's closer to the dates to bid?
