1)
DDP and DXDP have a pre-set amount of reimbursement.
2) Sushi costs more than the DxDP reimbursement.
3) Thus, it is not covered.
4) Premium and Platinum programs are different.
5) Although covering meals, they are not truly DDP programs.
6) So, they do cover appy's.
7) They are also honored at eateries not accepting DDP or DxDP.
8) They reimburse on a cost-basis, not a pre-set basis.
9) That is why Rainforest, Fulton's, etc accept them.
