Calmini doesn't do discounts - though there are a few tricks you can play...
1) Talk to Ramstein92
2) I ordered my Calmini bumper from Xterraparts and just had it shipped to them (they are about 5 minutes from my office - Richardson, TX... northern suburb of Dallas). I picked it up from their place and saved the $100+ shipping.
