NoMoreRack: Mystery Boxes Starting at $4 = Free
UPDATE: Not working as intended, you are going to have to add $20 worth of items to your cart then apply the credit, then remove the items you dont want so your total should not exceed $10 to be able to get it free
A while back we mentioned about a daily deal site called NoMoreRack giving a $10 credit when you sign up. If you sign up today you should also be able to get the $10 credit.
Well today they are offering Mystery Boxes starting at only $4.00 and shipping is only $2 per item. I would hurry though because these usually go quick! (plus they issued all existing accounts a $2 credit on Friday because the site was down for a while)
