E-Bates does seem to be the best portal to use when making Priceline bids, it offers 3% cash back which doesn’t compare to the old eBay Anything Points program but is the best offer standing. And best part is that rebates post quickly. You don’t have to wait until the hotel stay to see the 3% in your account. A successful bid on Wednesday yielded a rebate in my account Thursday night. Plus if you sign up for eBates they’ll give you $5 added on to your first rebate credit.
