It's not the Post Office's site. Private company. They're "approved" by the USPS.
The business next to us uses them. But they actually pay for fancy preprinted stamp backgrounds, driving their mailing costs way up.
I looked at them, and chose to stick with a meter (certainly not the overpriced P-B). You might print a few stamps on a sheet, say at a higher rate for large manila envelopes. Then later print a few more stamps on that same sheet at the regular rate. The system remembers which spots were used, which weren't. So far, so good.
But I saw a nuisance factor. Today, I just run an envelope thru a meter. With this stamps.com system, I'd need to feed a label sheet thru the printer, peel and stick the stamps on each envelope. Well, if you're mailing fewer than maybe 10 items a day, maybe this makes sense. We mail hundreds each month. Once a month, I'll have about 300 items to go out in one day. Not practical for us.
Yes, it does Express and other classes. Certified remains a pain. I find UPS easiest for overnight. Good riddance DHL.
EVERYONE SHOULD NOTE: The Post Office is phasing out acceptance of more meters at the end of this year. If your meter does not print a sort of burst code, it will not be accepted as of 1/1/09. It may already be too late to replace it before it cannot be used. Everyone should have rec'd notice from their vendor, and the USPS by now. But there's always a few that don't get the word. Especially when that word is sent thru the mails.
