With a little extra effort, it's possible to significantly reduce grocery and clothing expenses. In recent years, couponing has become all the rage among the fixed-income sect, so consider approaching a friend for tips or even attending a seminar. Along the same vein, make a habit of planning meals in advance, so you only buy what you need for lunches and dinners, rather than a bunch of random stuff that strikes your fancy. Next, consider cutting unnecessary items from your list. For example, rather than shell out cash on bottled water, fill up your own reusable container.
In terms of clothing, take an honest look at what your kids really need. A couple pairs of shoes is enough for each person, so resist the urge to promote your daughter's closet to Carrie Bradshaw status. Also, embrace the "new to me" mentality by purchasing used at thrift stores or consignment sales. Other great options are clothing swaps with other mothers and scouring the internet for deals you might not find in stores.
