Hey this is knetbd. is there anyone who can help me to make me understand how pin submit offer works and why they charge subscription money per week? say, an offer which describes to subscribe through phone carrier to win a i phone. or it may be something like for a battery booster. how these offers work?? can anyone explain please???

Hello,
the first PIN submit offer I saw, was an adult video offer and I always like to use that one as an example, as it nicely demonstrates the philosophy behind these types of offers. It offered access to a "members area" with adult videos for a weekly fee of 5 bucks or so, charged by the carrier. In the end, its nothing else just a different billing option, but instead of a credit card or check, here you agree to pay a one time or recuring fee that is included in you phone operators bill. Nothing more nothing less. You simply pay for a "product" with your phonebill, or its dedicted from your prepaid credit.
The product can be pretty much anything : ringtones, prize draws, apps, games, videos ... you name it.
Some products are charged for once, the other ones - especially the members areas - are charged, daily, weekly ... for as long as the subscriber doesnt cancel the subscription.
thanks matuloo. i got it. its ok for any membership type offers. but why they charge for to win an i-phone?? is that like you are going to have a lottery ticket for that 5 bucks for 7 days??
