This is how I bought BlindBag Minimates in the past. While it is expensive, it got the job done and not like I was hurting for parts, after.
Holy crap. Well. Not a fan of Todd's attitude on some stuff, and copying Minimates down to a T while they are in limbo sure is a choice. I will need to see how they look next to legit Minimates.
I am sure, much like Blokees, they will be on eBay for reasonable prices. It is usually 10-20 per Blokees to get the non super rare ones.
Like I said above, I would just buy the full set, since I would, any ways. But I also recognize that is dumb with my money, and not everyone can or would want to do that.
