That would be a great idea! I openend hundreds of them, it gets really anoying to open them one by one. So yes please! 

Yeah, English is not my motherlanguage so I didn't understand it in the first place but someone already explained it to me. I can't delete the post so I'm sorry but it is clear to me now. Just as I said before, ignore it ;)

That could be a good possibility! If that's true then everyone should ignore this post and then I've got my answer! I just always thought you could get that achievement for collecting all the cards. It is just a little bit confusing that it does not say wherefore you can get it. Thanks for your input :)

I thought of something like that in the first place too, but I have at least one item of every shop in my chest/inventory for a few months now. Still, it won't work, unfortunately :( 

This would be really handy for the Homework Corner we have too, as everyone who participates gets the same little gift!
