My $0.02 is that daily deal sites like this are tough to market, as you're only real ongoing customer base are those who want discounts. The tricky part is that they're a very diverse customer base so you can't base your pitch on what the products are and who should get the message. Like other people here have mentioned - if you had a niche it could make things easier. Ie: if you're providing deals on baking products only, then you can build some customer profiles (stay at home mums, japanese girls (don't ask, but it's a thing)), find where they gather and get your message in front of them consistently and build up a following.
