Fuel prices are sliding again as planting season continues

As planting season pushes on, fuel bills are getting cheaper.

Diesel has fallen nearly $0.03 per gallon over the last week. The nationwide average is around $3.51. Gasoline prices have also fallen, for the second straight week, coming down around $0.04 since last week, and holding at around $3.10 per gallon.

Analysts with GasBuddy say higher than normal volatility is likely to stick around for some time, but they note Americans are spending around $200 million less on fuel than this time last year.
