This Friday at Old Navy use this coupon http://www.facebook.com/photo.php?fbid=227672527260302&set=a.113766875317535.13418.113368148690741&type=1&theater to get up to 10 tanktops for 2$ each!! It's for women, girls and toddler girls!! Great deal to stock up for the summer - neat idea for gifts or even loot bags or craft stuff.
Also, a neat thing to do with tank tops is sew the bottom shut and use it as a bag! We turned a few of my daughters old tank tops into super cute purses that way!
