I'm confused.. I buy lots of crap on Ricardo .. The boxes arrive and the cost is printed - 7chf I look online at post.ch and it says the cost is 7chf .. Great..

But then I go to print my own label to send a package, the cost is 5.50chf no signature or 7.50 with signature..

What am i missing here.. Is it simply 1.50 cheaper to print your own at home??
