Nitro is going WAY BEYOND what I have ever heard ANY retailer do. AND GIVE GAS MONEY? Come on, ALWAYS DOUBLE CHECK the CG , If you had trouble before, why did you even buy this time !!!! And NO RECIEPT ? Is that the same as "the check is in the mail"? A lot of times the factory CG might be off. Man up, the manufacture makes mistakes just like we do. We have to take responsability too. Stop whinning..--Just don't buy from Nitro!! I think you'll be doing them a favor !! I'm sure a moderator will stop this, but somebody needs to stop this bashing. How many other retailers would go as for as John has. With NO reciept.
