Do you still use cash?

I cleaned out my wallet this weekend because it broke in half after about 5 years of use. I was amazed to find that I have had the same $20 bill in there since I withdrew it from the ATM in early August of last year. That means I haven’t used cash in nearly 5 months! I haven’t written a check in over a year and a half since I moved and never ordered new checks. I use Billpay and debit/credit cards and Mint to track it all. Yes I do realize that the credit card companies and bank are tracking my spending, but I’ll trade that for the convenience and budgeting I can do electronically.

So do you still use cash?
