Just don't shop at Whole Foods, unless you have to.
Have designated days/week to eat out, and stick to that plan.
Plan dinners, make a grocery list and stick to it.
Plan meals around what is one sale at your main grocery store.
No "frivolous" shopping. And when you do need clothes, go to a store like TJ Maxx or Marshall's.
Coupon: for example, I have not paid full price for laundry detergent, dish soap, toothpaste, shampoo, or conditioner for a year.... since I started couponing. This morning, I went to CVS and bought a Colgate toothpaste, mouthwash, and toothpaste, and Pantene shampoo and conditioner... for $5.13 TOTAL. Plus, got $5 in Extrabucks to use toward my next purchase. I don't have time to do this at all the stores, so I stick to the two where I do the most shopping: at Harris Teeter and CVS.
No more coffee shops.... make coffee at home for a fraction of the cost.
Take water/snacks in the car so you don't eat out. I use my cooler every day.
Get a reusable water bottle for everyone in your family.
GROUPON... I love this concept and the website. Its how we're doing a lot of fun stuff with the kids this summer. (i.e. water parks, restaurants, boat rides, etc.).
Good luck to you.
