Thanks Curt for sharing GrabSomeDeals.
You can get the 70% easily, you don't have to be a premium member. Go to the bottom of the deal page and you'll see the steps to get the 70% discount. Basically what you have to do is to fill your name(if you are a registered user you don't have to), click on 'Share this deal with your friends by email', choose 5 friends you want to share the premium discount by email, press send than click 'Activate the premium discount for me and my friends'.
That's all, you and those 5 friends get the 70% discount.
Yes, the paid premium membership is not yet available but you can get it for free if you share deals with your friends on facebook, twitter or email. When you reach 10 referrals you'll become a premium user for 3 months.
If you have suggestions or questions you can post here or contact me using the contact form on GrabSomeDeals.com
