I pay most of my bills by automatic deductions from my checking account. Loans, car and house payments and utility bills are all paid this way. Others like credit cards I can pay by going directly to their website and paying with an online account or PayPal. I use the USPS for all my packaging needs and am able to save on gas since it is within walking distance from my home. I am sure that in time we will loose our post office and will have to drive to the next county with a larger town and it may be a bit of an inconvenience but as long as we can still order package pickup and postage stamps online I think it will be fairly easy to adjust to.
The internet is the reason the post office is failing. But in the 1970's we all screamed for new ways to save the trees. That done, I am glad for the changes!
