We thought you all might like this comment on gas prices and overall spending from one of our tax contacts in the Great Plains:

I think of savings on gas as pre-spent money. Spending on gas is inelastic, and the average consumer saves about $1,500 a year [for every dollar drop in price]. For the working-class person that $1,500 may have already been spent. Now, instead of being $150 in the hole each month, they are only in for $25. That would explain why the $500 payment back in 2001 didn’t provide substantial gains, and why we didn’t see an increase in spending when gas prices halved.
