Facebook Coupons

Is there is any way to get facebook coupons in a systematic way?

For Ex:
1.Create x accounts
2.Warm up the accounts for x days
3. Do X to get the coupons

And how to maintain this

Second Q: Any vendors to get coupons for a cheap price?

Thanks in advance

We got one for one of our FB pages recently, a £15 free ad credit. Not really ever seen much else around though now.
