Seems silly to me. The limit is 45k worth of bonds a year. 30k Series I, 15k Series EE. So I get 1.8 roundtrips locking up 45K of cash at rates under 2% between 4-6 months (assuming you use the credit card grace period to the max)? It is a nice perk, but if I had 45K in cash lying around I wouldn't be concerned with 1.8 roundtrips. I'd be more worried about that analyst who figured AA would be short of cash by the end of 2003. Assuming worst case, what would happen to all those people who have cash in the AA Money Market Fund???
