Food I dunno someone give me ideas how much do you spend a month just for one person? well actually I have a roommate and we both love to cook so I dunno. i was thinking we’d probably spend 300 a month so split in two about 150 but I wanna know what other people spend.

I feel like I’ve forgotten something but I don’t know, maybe not if anyone has any ideas for me please help. Thanks.

When are the plug in hybrids arriving to the market? I heard something about Fuel and Hydrogen cell cars, when are these cars supposed to come out? I want something around 100 mpg.
