Actually, the "interest" is the $300 discount for those who truly had discretionary money to put into a gun not yet in production. If your money was not "discretionary", it doesn't seem to me that it is Tony's fault. The $300 discount on the $2495 purchase price is about 12%. If your gun takes two full years to delivery, you still earn 6% per annum. Not bad in today's world of 2% passbook interest. Delivery in one year would be a whoppng 12% interest, if you didn't bail out early.
