Anyone in the UK want to trade stamps with me?

Hi, I'm new here but I've been doing autograph requests TTM off and on for a few years now. I want to send some requests to the UK but it's such a hassle to get the required postage for the SASE. For a photo in a large envelope weighing 2 oz., the SASE will need postage covering £3.15 so I tried purchasing some international stamps off the Royal Mail website but they won't ship to the US. I also looked for stamps on eBay but that was no help since those stamps are primarily for collectors. If anyone in the UK is looking for USPS stamps, please let me know and we can figure out a way to help each other. I've heard that I may be able to purchase 1st Class stamp books on the Royal Mail website but I will have to purchase several of them and I will be severely overpaying for postage so hopefully I won't have to do that. Thanks.
