Anyone that uses Facebook ,check out their ads for stamps. Takes about 2 weeks or so. But you can get like 400 USA stamps with shipping for around $22 to $25 bucks. I have bought them 3 times .AND YES YOU DO GET 400 STAMPS. I USE them a lot because for me it’s easier for me then to take to the post office . Because the one in my small town, acts like they hate to do anything that even looks like work 🤬🤬🤬. So I buy my own. They are useable stamps. So far except for A RETURN TO SENDER FOR NOT HAVING THE RIGHT ADDRESS. They do work and I have never had the post office say SORRY BUT THEY WONT WORK.👍👍👍… So if you up to saving money , that’s the way to go. I put 3 one the outside envelope and 3 on the return one. 👍👍👍. Never had they say not enough postage 😁😁😁👍👍👍. Just trying to be helpful.. Best of luck to all..
