My employer partnered with Good Natured Family Farms for a Community Supported Agriculture (http://www.goodnatured.net/) to provide organic meats, fruits, veggies, dairy, grains, and eggs delivered to work weekly at $21/wk. (Payroll deduction of course.) They started this the first week of June and runs through the end of September.
We save 5-30% each week - plus it's delivered. I love the fact that everything is organic - even the meat. Bonus is we're getting produce we wouldn't purposefully buy at the store: yellow squash, zucchini, egg plant, swiss chard to name a few. The unexpected bonus is we've added new meals to our rotation - and K and I have started to enjoy cooking/prepping dinner together.
What's even more amazing is the kids know when it's Tuesday - 'cause I bring home food. If there's cheese we cut it up into cubes/sticks and start snacking. This last Tues. we got peaches....we ate 1/2 of them that night. I had forgotten how good fresh peaches are. K even got T hooked on slice tomatoes with a little salt on them.
Now this is not a regional nor midwest thing - but it's federally sponsored. Search Community Supported Agriculture and you'll get a ton of hits. I strongly urge you to recommend this great opportunity to your employer as it's a great way to give back to your community, and do something good for yourself!
