Introducing Lensrentals HD (Lensrentals Blog)

LensRentals HD is a shipping discount program. By signing up, you’ll get free Standard Shipping on all the orders you place for one year, and you’ll even save 50% on all FedEx Overnight shipping.

I've held off on renting certain things, flash units, camera bodies, lenses, etc., because quite often the shipping cost was half the cost of the rental. This might change things for me.
