I'm seeing many Google, Facebook, etc. vochers/coupons being sold. IE Google Adwords $50 vouchers for $3, Facebook $25 dollar vochers $5. Can someone explain what they actually are, and how they work, and how people get ahold of them (curious to if they are legit or not). Thanks in advance!
Vouchers are used for that particular item, for example a $50 google adwords voucher would get you $50 credit in google adwords ($45 minus the $5 fee.) Same for facebook and the others (except I dunno if they have a fee included.) You can obtain them through emails (if you've signed up to google's email program) or through hosting companies which provide them for free. They work by using the code that people will give you in the corresponding sale, then the credit will be applied to your account.
