Went to the post office to purchase my holiday stamps for Christmas cards & inquired about postage for STD & Invitations. The lady was nice enough to give me a heads up that there is a postage increase by the end of January. The forever stamps will be going up 3 cents each, making it a total of 60 cents more per pack. I am planning to send my STDs shortly after the new year, so I will be purchasing my stamps soon. She also suggested I buy additional forever stamps now, to put on my response card envelopes. I just thought I'd pass along the money saving advice!
