Auto Bill Pay
I know there are services where you can have your bank send money to pay your bills each month. I do have that set up for my car payment. My mortgage and utilities directly bill my checking account, which is going at it from the other side. Most of my other bills are automatically charged to my credit card, and I go online to the credit card web page to have them draw money from my bank account.
I've never had anyone try to charge me for letting them draw money from my checking account, or to charge my credit card.
Yes, it requires that you keep an eye on things, but I have all of my credit card, mortgage, and bank accounts online so I can check them easily.
I must save 10 stamps a month which is $4.90, plus the trouble to get them in envelopes, to the mailbox, and hoping they arrive on time.
Are there any other tricks you use to keep your ever-increasing pile of billing in line?
