3. Complete an offer. I suggest stamps.com offer. It's a free trial. If you like it, keep it, if not cancel not sooner than 22 days, but no later than 28. Has to be on a week day. You also have to print some postage. I printed all $5 worth of free postage given before I canceled. They work. Doesn't cost anything to complete the trial. You will be billed $15 if you don't cancel in the 22-28 day period.
4. Get 8-14 people to do the same, depends on the prize you want for the amount of people. Can't be from the same computer or same address. They log IPs so your account will be on hold permanently if someone signs up under you from the same computer or resides at the same mailing address.
5. Wait for PS3 (cash is an option too).
It works. Research TRAINN or Transcendent Innovations for proof. They are the company for this offer. Totally legit, but most people don't believe it. I just ask you sign up under me.
