I have a cupon which expire o July 1. But every time I try it it say the cupon is expired already. What the point to send cupon to the community if we can't use it?

That happens sometimes. However, as David suggested, bring in the coupon to the restaurant or call and explain your situation to the employee. From personal experience, the employees usually are very helpful when it comes to situations like these.

Of course. The cupon say when you make your order online.

Sounds like you're trying to use it online, Miss Rodriguez? I would suggest calling, or bringing the coupon in and asking.
