Do you have a strategy for how you use the free play you get from locals casinos where you life?

For example, there are casinos with daily offers and weekly offers. Do you ever show up at the casinos to claim the free play credits and instead of playing them then and there you bank them?

How long can you bank free credits for?

I know of one casino that issues free play in the form of "tickets" which you literally can put in your wallet and save for another day.

I know of another casino that has a combination of free play offers. While you must show up on particular days to claim them, they need not be played immediately.

Do you ever "bank credits" with the idea of having a larger "free play bankroll" for a future date?

Or do you claim them and use them?

What's your strategy and why?
