OK, now don't get excited about this, since I was unable to confirm it online. I received this in email, and am just waiting to see if it's right. I checked Snopes and the IRS website, and googled extensively in vain. Everything I heard before seemed to say the rebates would be sent out from May through July, not July through September. Having said that, I'll share the information with you anyway. Just because.
If you're waiting for your income tax refund (I know, I know... smart people don't try to get a refund; but there are a lot of stupid people like me who love to get money back) you can find out if it's been received, whether it's being processed, or if it's on its way to you by going HERE.
