Having a webshop means sending stuff away - in my case to all corners of the world. (To a lot of them, at least.) Which can mean a multitude of different tariffs depending on the size, weight, and place the package has to go to.
Which means that sticking the appropriate stamps onto a package... can take a bit of research beforehand. I ship most things using the German Post (which is now called either Post or DHL), and for any address questions I go and consult
Frank's Compulsive Guide to Postal Addresses (and thank you so, so much for that, Frank!).
In the end, packing things up, putting the address and appropriate postage on a package are a task that needs concentration (so you get it all right) but is still sort of dull. Which means anything that makes it more fun is a nice thing, and much appreciated.
And my, have I been having fun recently... because the German Post brought out an extra-special fancy stamp featuring
Asterix this year, and I've bought a small stack of them. So if you ordered something at my shop, and the postage I have to stick onto it falls into the right tier, your package might look something like this:
These stamps always make me smile, and I'm really happy that I get to use them on actual mail that goes out to hopefully make other people smile as well - even if it's just for a few minutes before tossing the package into the paper recycling. (Though if you know a stamp collector, they might appreciate it, too...)
