Here are a few ideas. Try to buy some sardines and wild caught fish that is canned. If you have a Whole Foods near you they have some pretty good deals on canned fish that is very low in mercury contamination, BPA free cans, and are great sources of n3. For grass fed beef try to go for the fattier cuts of ground beef as they are cheaper than the lean cuts of ground beef. When it comes to steaks try to avoid the rib eye or NY steaks since they tend to be the more expensive cuts and go for the London Broil, top sirloin, chuck. They may not be as marbled as the rib eyes but if you season and cook them right they are really yummy and you will get more bang for your buck.
You can also buy in bulk and do some sort of cowshare program where you buy 25 lbs of beef or a 1/4 cow which helps save a lot. I have friends who buy whole cows and divide it among our group and we tend to save a little that way.
Costco has some pretty good deals on organic chickens, organic ground beef, wild caught salmon and organic eggs.
Also you can sign up for Whole Foods newsletter to update you on weekly deals.

People say I am on a "crazy" diet. What is so crazy about eating veggies, fruits, seafood and organ meats? Just because I don't eat whole wheat and processed food doesn't make my diet "crazy". Maybe everyone else with a SAD are the "crazy" ones for putting that junk in their system.
