I might be receiving some unexpected funds soon. It will definitely help with bills but the only problem is it will be in the form of cash. How would you go about using this money?

I put pretty much everything on my credit cards and use online banking to pay all my bills so cash is rarely utilized. And if I suddenly deposit this to my bank so randomly I'm afraid it might flag me for something and end up getting account frozen.

What would you guys spend it on or how would you go about utilizing this extra bit of help?
