Why don't people use commemorative stamps on their mail anymore?

I've noticed on my own personal mail that I hardly get any that have been posted using commemorative stamps - the beautiful, usually larger size stamps that honor an event, a person or some other occasion.

I thought about this for a while, and then realized that the USPS is not making it convenient to use them on mail. When you go into a post office to buy stamps, they usually try to sell you the small definitive stamps - flags, etc. - and if you want to buy commemoratives you have to specifically ask for them.

My own post office only sells one type of commemorative stamp, even though there are probably dozens of different commemoratives currently available for use - that is all they stock.

It's no wonder that postally used commemorative stamps are getting harder and harder to find.

Stamp collectors should write to the USPS and see if these policies can be changed.
