Today’s Detroit Groupon is a $40 certificate to ShoeBuy for only $20! The best part about this particular certificate is that it does not have to be used all at once. You can apply the certificate, place your order, and use anything leftover later. Plus, they offer free shipping!
There is a limit of one per person and these are only valid online. This offer is available today only, so grab it while you can!
(Thanks Marc!)
