Garage Sales/Thrift Shops
Angie Zalewski, co-founder of the Frugal Family Network, Inc. and coauthor of Cheap Talk with the Frugal Friends, suggests looking for garage sales that have an abundance of baby items. "If they are selling their baby stuff, they are most likely concluding the baby days of their family's life and will probably have maternity wear available as well. If you don't see any, ask," says Zalewski.
Another source for cheap maternity clothes are thrift stores. Zalewski recommends church-owned stores or stores run by small organizations for the best prices.
