My friend did a study with Memrise at their Headquarters in East London not too long ago and got an awesome purple free t shirt! I really want one because not only is it cool but it represents my daily routine. I think EVERY pro-member should be entitled to one. That said, where can I get one?!

I am sure you will get an answer on how to proceed with this.
I’ve always wondered why there isn’t a merchandise shop? I’d rock a Memrise t-shirt or canvas bag!
