You could build a community and reward them with small amounts of bitcoin for validating deals, providing real reviews, etc. You could charge small amounts of bitcoin to advertisers to move their ad or product higher on your page. If a reseller wants to list a deal on your page, you could charge them a small amount of bitcoin to prevent junk deals from being submitted. You could also charge a small amount of bitcoin for access to an elite deal notification list, like for example if a store is selling a GoPro HERO4 Silver for $175, they could get an alert, etc. You could reward people for submitting a great deal that actually works... nothing is worse than a 20% off "coupon code" that never works.
