I was there at Iows Gas when this guy pulled out I believe 30 to 40 if these and they were numbered 1 2 and 3 3s were 1500 2s were 2000 and 1 were 2500 if you bought more than 1 he would take off 10% so guys were teaming up to get the discount. I would have bought 1 but I had earlier bought a conoco and kinda blew my budget.
