I say (Andrew may disagree) if you find a good deal on Minibots, go get them.
If Andrew didn't pull a miracle, I would have put off mini-bots until the end. Who really needs mini-bots? They're small, crappy little transformers. The problem is that no collection is complete without them.
The problem is that everybody puts them off until the end, you see them everywhere for a while, then all of a sudden...GONE!
I put off the keychain ones, and now I'm SOL.
