Buy a solar oven! I've searched to find the most cost effective way of cooking for single moms (and everyone else!). These are a good price & work really well! Email me for a flyer. I sell the SOS Sport & Global Sun solar ovens. Prices include shipping to your door. https://sites.google.com/site/singlemompreparedness/solar-ovens.

Here's the pile of items I got at Walgreens today. The Neosporin & Carefree are great items to put in your storage. This pile was not only free, but I'll make $5 on it after I mail in the rebate. Look on sites such as Money Saving Mom to find details on the rebates & coupons necessary to get these deals!
The normal cost on this was $33.
