I have created a cashback website that pays you to sign up for free internet offers and pays you cashback on shopping.

It has several unique selling points
1. No minimum amount before you get paid (most sites have a minimum #20 threshold) before payment.
2. The largest amount of free offers of any like minded site.
3. The highest referral payout (refer someone and get 50% of whatever they earn forever.
4. An International site - has offers (in English only at present) for every Country in the World.

I have having great difficulty in promoting my site so I am looking for any advice to help.

The site is at Steves Free Stuff
