I really like the lightweight and waterproof polyester shopping bags from Envirosax. They roll up into a small tube and a snap closure keeps them that way until you're ready to use them. They come 5 bags to a pouch and the pouch isn't much bigger than the size of a small cosmetic bag, making it convenient to toss into your handbag so you'll always have carry-bags ready when you need them. What's even better though is that during the month of November Envirosax will donate $1 from the sale of every pouch to the ASPCA to help Foreclosure Pets. Foreclosure Pets is the term applied to the rising number of animals left behind to fend for themselves in empty foreclosed homes. When found, these pets are brought to local animal shelters often in desperate need of medical attention, but with dwindling donations, the shelters are having a difficult time covering medical costs, food and shelter. Help yourself while helping animals in need. For more info on Envirosax or to purchase a pouch, visit www.envirosax.com
