I'm not really sure of this because I've never had pure molly (only pills) or methylone, but from what I've read they are fairly similar only that methylone doesn't quite have the "push" molly does. Anyways, point being, is the price difference really worth it? If you know where to look, methylone can be had for less than $6/gram if bought in bulk, while molly can be $60-100/gram. Seems like a fair point to me...
