Amazon has a number of bras on sale for $5 including Lilyette, Maidenform, Bali, and Vanity Fair. If you're willing to spend a few extra bucks, there are some nice bras for $6-$8 also. They qualify for the Super Saver Free Shipping if you spend $25.
I'm at Stay at Home Mom who feels my way of contributing to the family is to save us money and I love to share my bargains with my friends and family.
