Another in a series of posts to make you look like a better mom. Although this tip is good for pretty much everyone.
This weekend I needed groceries, baby shoes, TP and sunscreen. I had a coupon about to expire for the grocery store, so I went there for the food. I went to a box store with an incorporated shoe store for the shoes. I intended to buy the sundries there, but for some reason they didn't sell those items (or they made it impossible to find - several laps later, I gave up).
So today's lunch break was dedicated to buying TP and sunscreen. It would have been much easier to make one trip and buy all the things. Plus, I made impulse buys at each of the three stores, so I would also have saved money.
Shopping at one store does sometimes require planning. For example, had I used the coupon last week I could have avoided the grocery store this week and just picked up fresh things at Target. And it may mean you can't play the coupon game (a habit I think sounds cool but have never actually done), but your sanity is better. Plan ahead. Go to one store per week (or every few days if you need). Buy paper goods at the grocery or groceries at the big box store - the savings will even out, and your sanity will be worth it.
