I have 479,000 points. I saw a post about the rewards for Thurs, but it says limit 1 per member. Does that mean I can only get 1 reward total, or 1 Denny's cert, and 1 Toys R Us, etc? Does this have to be a certain time or a certain way? Is it difficult to get a reward with my points? I would like to get towards my DW vacation in Oct. What should I go for? Thanks!
