I seem to be a sucker for many of the Royal Mail stamp issues. I don't need to buy more stamps yet the new issues generally tempt me. I buy the stamps to use, eventually. I am not going to admit how many stamps I have available for use, but I don't fear running out of stamps.
The only good thing, perhaps, about the current international airmail postage rate is that it is just 2 first class stamps for most of my overseas mail. This means I have a ton of choice when it comes to stamps. Dare I use a DC Comics stamp next to a Marvel stamp?
Or, I could just use the £1.70 postage stamps, but there isn't as much variety as there is in first class stamps.
