There are several different ways to cut costs:-
1) If one has any raw-foodists nearby, one can bulk-buy foods like meats sharing the costs between people, thus cutting down on delivery-costs.
2) Practice Intermittent Fasting. When eating raw, one doesn't necessarily need to eat as much as on a cooked-diet, so eating only one meal a day or doing alternate-day fasting makes a difference.
3) Buy only from small farms as they won't charge extra retail-costs like butcher's etc. do. Often the "organic" labele doesn't necessarily mean much. I've encountered small-time farmers who weren't necessarily "organic" by category but who didn't feed their animals with hormones/antibiotics etc.(because they couldn't afford them), and fed their animalson 100% pastured diets,and the meats/eggs etc. of some of those farmers was actually much better in quality(and cheapness of price)than the big organic-status agricombines - the latter often try to loosen the organic-category regulations out of a desire for profit,and get away with all sorts of other dubious practices.
4) Eat low-carb - I would spend far more on rawfood if I included too much plant-food in the diet.Raw plant-food seems to increase the appetite.
