Beginning in August, the US Postal Service will cut back on Saturday mail delivery and collection. This may not seem like a big deal, but it could change how you pay your bills. Make sure that the change doesn't catch you by surprise.
If you pay bills in the mail, it'll take a little longer for those payments to get from your house to your payee. If the timing is right (or wrong), a missed Saturday could mean that your payment arrives late. Of course, late payments often cause additional fees, and they can even begin to affect your credit.
Kelli B. Grant from MarketWatch.com does a nice job of explaining exactly what could go wrong. She notes that even if you use an online bill payment service, some of those payments are sent by regular mail -- not electronically -- so you may need to make some changes if you've been cutting things close.
