The Dillard's American Express card can be rather useful. Particularly if one manages to reach the "Elite" stage by shopping frequently enough to have spent the required threshold for the aforementioned status.
The perks are competetive, both within and without Dillard's in todays plastic driven culture. And since there is no annual fee, it can be a fair alternative to actually not having to pay AMEX for one of their own fee based cards. However, the APR on the other hand is nothing to write home about.
But all in all if used sensibly, it can be a handy, utilitarian option.
