Okay, I think I found a loophole through facebook limiting you ad coupons. My main account cannot use ad coupons because I recently ran an ad campaign via credit card. To bypass this, I deactivated my ads account on my main profile (I can reactivate later) but what this did is removed my primary payment option. I then created a new facebook account, and made myself an ad manager on my page in which I am promoting. Now on that new account, I added an ad coupon which worked, and now I can start ads if i set my secondary payment option as my credit card. Then once this $50 is done, I could make a new account and do it all over again, right?
