Re: save money on stamp production

There is no net savings on "Lick and Stick" stamps, because the stamps -- while, initially, cheaper to produce -- are much more easily damaged by humidity or moisture. In extreme cases, they stick to each other and cannot be separated without damage, causing them to have to be replaced by the Postal Service. In lesser cases, they lose their ability to stick, leading to customers sticking them on with glue or tape -- which is prohibited because it prevents the stamp from being cancelled and/or gums up automated mail-processing equipment -- or the stamps falling off in the mail, which can result in the item being returned to the sender for additional postage, which delays the mail, is unfair to the mailer and unduly expensive for USPS.

Re: Is this another Commercial ?

Certified Mail requires a signature, whereas Delivery Confirmation is merely scanned before being placed in your mailbox. Obtaining a signature is much more time-intensive, especially since many people are not home during the day, so a notice has to be left, offering them the option of picking it up at the Post Office or having it brought back out. Sometimes, there is no response to the first notice, so a second notice is delivered. If there is no response to the second notice, the item must be returned to the sender. That's why Certified Mail costs more; it is much more labor intensive.
