but I didn't so I'll share.
I was sending out the little quiltlet I made the other day and couldn't be bothered to go to the post office, so I weighed it and thought I'd find out how much it is and just cover it in stamps. So Googled how much is costs to send a small package to Germany and found the POST OFFICE WEBSITE
You just put in the weight, where it's going, pay by credit card (debit card if it's under £5) and then print it off. Stick it on with sticky tape and if it fits through a letter box, you're sorted. Even if it doesn't, all you have to do is take it to the part of the Post Office for parcels and just walk away. You can even choose what size of label you want to stick on. Easy. You have the option of leaving your credit card details on their site or not, up to you how much you trust them.
