Debi - The main expense of MRC is the initial payment, which it sounds like you've already done, and the cost of the drink supplements. I actually save money on my food expenses because the processed foods are more expensive than what we can eat.
As far as the supplements go, you can buy them online for cheaper than you can buy them in the center. The center won't love that, and I've never done it, so I have no advice on that, but they can't make you buy things from them. It will invalidate your contract's guarentee if you do that as well...but so will eating one tiny thing off plan, so its kinda impossible not to.
Diet Direct is where you can buy the drink supplements online. They are the same products, just with a different label. Someone will pop in here with more info on that I'm sure
