Whether you send many first-class letters or just a couple a year, this is your deal. With postage at 78 cents and almost certain to rise here are ten forever stamps for 50 cents each. I’ll pay the shipping and also include mint stamps with a value equal to your sales tax. If your tax is 6% or higher that will be enough to pay the «second ounce postage» (currently 29 cents additional) on a two-ounce oversize greeting card. Forget going to the post office. You can mail a letter from home for just 50 cents like it was 2018 all over again.
