The Canon DSLRs are not the only Canon cameras eligible for the Pixma AMEX Mail-In Rebate offers. Some of the more serious Powershots with RAW are also eligible. B&H Photo has one such bundle centered on the Canon G16. You pay $730, submit a mail-in rebate, and receive a $350 American Express Gift Card a few weeks later, making this a $380 after $350 MIR offer.
For that, you receive the Canon G16, the Canon Pixma PRO 100 printer, a 50pk 13×19″ Canon photo paper, and a 32GB Transcend SD card (and the $350 AMEX Gift Card via mail-in rebate).
