I swung by the store this morning and got $25 worth of supplies, including the following...
3 limes$.22 each
4 kale bunches $1.18 each
4 bags of green apples $3.98 each
2 cucumbers $.78 each
I threw in a half a celery bunch, and a thumbprint size piece of ginger from home.
I juiced it all and I got the equivalent of 1 1/4 of these containers shown. They are like a standard gallon size drink pitcher. This much juice should last one person 2 or 2 1/2 days.
It really is no more expensive than what most people spend on grocery food or eating out, yet it contains more live nutrients than most people on the go eat in a month.
