Question about PIN Codes

[stace1214]

So I recieved my first pin code in my email today....it's the free dining one that lots of people got. Unfortunately, I can't use it. Here's my question...if we don't use it, we will continue to get them every once in a while or will that be it?

Thanks for your help!!

Pin codes are completely random. You may get more, you may not...
