I almost never use cash anymore outside of strip clubs. The main thing I use cash for other than strip clubs are a few odd things like vending machines, the farmer market, or if I want a quick Sincweiser at a bar since tabs sometimes require a minimum billing amount like $10.
I strictly use credit cards for 95% of my purchases nowadays. There are several advantages. (1) Credit cards give rewards like free flights, free hotel nights, cash back, etc. (2) It is quicker to swipe a card then count out money. (3) I save time not having to keep going to banks or ATM's to replenish cash. (4) The wallet is alot thinner with a couple credit cards versus wads of cash.
What things do you guys buy with cash?


I still tip in cash even if I put the tab on the card. That way I know the server is getting what I left for them. Other than that, I rarely carry cash.
