3. Coupon or Groupon. I'm not talking about the crazy couponing strategies seen on reality tv (Seriously though, where do they get the time, energy, and fliers for that? And who needs 50 boxes of cake mix?). I don't line up my shopping with weekly sales or coupons. One thing I do every week before we head to the store, though, is go to coupons.com and print a few coupons. I print anything I think we might need in the next month or so, and then when it's on our list I just happen to have a coupon. Sometimes the stars align and I find coupons for what I need that week, and other times we don't use any. It's not rocket science, nor is it difficult, but it has saved me from every paying full price for cereal or soap. Cost savings per year: $50
I am not a weathered Groupon user, but I have purchased a few experience/food related groupons, and they were great deals. It's a great way to pay for a date night dinner at half price or a trip to the water park at BOGO. Sign up is free, and you only buy something when it's a perfect fit. Our best Groupon purchase? Meat from a local market at half price.
