The amount of cents that a postage stamp went up.
The amount of days that I went to buy stamps and missed getting the cheaper price.
I miss living in a small town where there was a sign on the post office to announce postage stamp increases and I went there daily to pick up my mail so I saw those signs. Sigh.
*I know there are now FOREVER stamps, but I was trying to use up some old stamps I found and I was proud of myself for getting the right amount on the envelopes ready to mail without buying 1 cent stamps. Now I need 1 cent stamps. Sigh.
On the bright side those 32 cent stamps I found will mail a postcard now. I won't think about being able to mail a letter for that price when I was in college.
