I'm a little unsure about the whole Rebel Rebate thing. If for example I bought the Rebel ($100 rebate), the 28-135mm lens ($15 rebate), and 16-35mm lens ($50 rebate), then I would triple the value of all three rebates and end up with $495 of total rebates?! Or did I get that wrong? At first I thought it was only triple the D-rebel rebate or a max savings of $300, but now I'm not sure. Also, does anyone know if these items have to be purchased from the same place/seller? Thanks!
