Yes, on some credit cards it's actual 2% cash - Apple Credit Card, Fidelity.

Amazon gives you 5% back for using their credit card, it's criminal not to use it.

If you buy a lot of equipment or expensive equipment - B&H credit card covers sales tax! I.e. 10% for my area! (I don't use it since I don't buy that much, but still it's an option)
