If you're headed to the mall on Saturday, you may want to stop by the cosmetics counter at the Bay -- if you turn in an old tube of mascara they'll give you a $10 voucher towards a new mascara. Finally, a purpose for those old, dried-out tubes of mascara hanging around in our handbags and bathroom drawers!

The promo is limited to 100 vouchers per Bay location. The voucher is valid July 11-24.
