Get Powerbulbs discount coupon for 10% less on next purchase

I got my Powerbulbs by using one of Ozbargain coupons from DRL. When I got it, I was surprised to find a discount coupon for Powerbulb next purchase or to be exact, it states 'future orders'. It indicates that I will get 10% discount if I will buy another items from them. Actually, I don't know if this is helpful to you but I can assure you that they don't usually send out like this. So, I guess it will be fine to apply it on orders. Well, regarding the promo validity date, I can't seem to find it on the card. By the way, you might interested with different coupon that ends on 26th with 20% discount on orders more than $80 (HIGHLOW20). You can go ahead use them and enjoy the big savings: http://files.ozbargain.com.au/upload/70154/24544/2014-08-13_15.48.19.jpg
