I use Stamps.com Yes, I knew they were real stamps. I usually give them to my boyfriend (btw, that is my granddaughter in the picture, not me :) this time of year cuz he has lots of cards to mail out. Plus he is one of the few holdouts who still pays his bills by mail.
Your granddaughter is beautiful....I am 58 and pay bills online thru credit union...I have used PayPal shipping for packages but have not tried stamps.com...where do you get the stamp paper from? Do you order it off their website? Our post office has a self serve kiosk that I use.
