Where can you get cute clothes for a good price for a teen or tween?
Consignment shops. These stores have a great variety for the best price (especially for brand names! You could get a shirt of a $20 value from Abercombie, for just $4!). Also, your kids won't even know where you got the clothes from.
Down East!! or Old Navy is good too.
Are you a teen or tween? Different stores for different ages.
