Currently, Ebay is offering $50 Hotels.com gift cards for $40! Hotels.com has the best inventory of any OTA that I’ve seen, so this basically nets to an extra 20% discount on any hotel that you want, in addition to portal cashback and any other promotions Hotels.com may be offering at the time you book. You can find the deal here:
