IMO, the only time you should use cash is if you are buying where a credit card is not accepted...like meeting your "guy" in a dark ally to support you "habit". Other than that, any legal purchase should be done with a credit card. I normally get anywhere between $250 and $1000 CASH each year from my credit card points.
To answer your question about a stash, yes, I do have one...but it is not in cash, it is in a bank account she is not aware of.
