^ Personally if it's really bad I'd send it back. I had to do that with one of my Unite Warriors sets and they promptly refunded my purchase and return shipping.

If it's not bad enough to return but still has issues which it sounds like most do then I'd take the 25% refund.

Let's hope the next $300 Transformers product from TT doesn't have issues. (that would be MP Dinobot)
