What's the grip for the t1i?
And is it advantageous to buy online for things like that?

Yes, it is always advantageous to buy online, especially in the U.S. You avoid taxes
The advantage: longer battery, improved ergonomics. Most importantly, a more 'pro' looking camera, which is great when you're into making money off it.
