$300 is a good start! The more you "churn", the more you'll earn

I don't think $300 will earn you $1000, that was just an example of a good starting place to learn.
For Ebay bucks, when a 5x (10%) offer rolls around, you can earn up to $100 per transaction (I think, someone correct me if I'm wrong here), So $1000 x 10% = $100 Ebay bucks. You can earn $500/quarter. So if you're churning $1000 through, earning $500/quarter, there's your $1000 that you're hoping to earn. Plus of course Ebates and all that. So there's an idea, too.
