Yesterday I reserved a motel room via Priceline. An hour later I found the identical room listed for $5 less (excluding taxes and fees on both sites) on Expedia and decided to make a claim with Priceline. They put me on hold while they checked the Expedia website. After a long wait, they claimed the Expedia website listed the same price. When I objected (I was looking at the Expedia screen on my computer), they told me to renew my screen. They insisted the price had been updated in the course of our conversation. (The update did occur about an hour later.) Evidently, they contacted the hotel and had them update their price on Expedia. Bottom line, they did not honor the terms of their guarantee and committed fraud.
