I just got a catelogue in the mail from Bumpto3 from the makers of grobag! Its because I'm in the coles baby club I guess, so there will be heaps of others getting them.
Its got all the grobags in it, there are a few patterns and weights. They do mail order, so if you want a new one, go to their website and you should be able to get one. They look pretty good - but so they should for about $90!!
