Instructions:Add 5 items to your cart at Deal Extreme and apply the discount code in there. It shows a $2 discount!
This is great if you want to order lots of low value items. For example, I tested it on 5 of those flashlight pigs and it brought the order total down from $3.90 to $1.85 with free delivery too.
Just so you know, Deal Extreme is a Hong Kong based site, but it ships worldwide.
