LOL.. Sorry, yes i like sorting them by price... i didn't elaborate my question as what the benefit is of the A & B buttons separating the KAN and Non-KAN stamps? I was expecting there is a reason for that option? Thx!
The daily KAN stamps disappear if you don't use them and you can get KAN stamps for cheaper than non-KAN. It's just different ways to sort them, depending on individual's preferences. You got the explanation with the upgrade and testing them will tell you which you like the best. I like the A button.
