Where to buy Facebook Vouchers for cheap and what are the limitations ?
Hi Nabeel, thanks for your question.
Do you mean Facebook Ads Voucher for Facebook Advertising Credit? Yes, it is legal but you have to beware that some sellers sell vouchers that don't work.
Try to search on Google since I don't use Facebook Ads before because advertise on social networking sites before because people trust ads on social networking sites the least. You can read statistics on my blog (link below).
