I go to a botique grocery store that makes fresh juice mixes in jars. It's like 3 bucks.
I looked at getting a juicer, but, it was just going to become one more thing to clean and I don't think I'd really save any money using it like Adam said, so, I nicked it.
I still go to Starbucks semi-often and get knocked over for a 3.50 coffee.
When I was young and broke, I'd live an entire week on like 6-7 bucks. Bread, peanut butter, mashmellow fluf, kool-aid, maybe some bread wit sugar on it for desert.
