I cannot believe I wasted my time trying to purchase a cruise through this site, only for them to deny me my cash back. I made a purchase back in December of 2017 through ebates when they were offering a 37% cash back. I distinctly remember logging on to my ebates account and going to entertainment.com/cruises to make this purchase. Now, months later when I am trying to retrieve my cash back, they magically claim that my order number was invalid and cannot track my cash back. These people are unprofessional and dishonest. Ebates tried to communicate with them and entertainment refuses to even acknowledge any fault or look into the matter any further. I have emailed them to recheck their systems but I doubt anything will come of it. If you chose to make any large purchases through this site, beware. They will lie and claim that your confirmation number is invalid and your cash back will not be honored. I canceled my membership and will never recommend them to anyone.
