There’s a hot deal at Amazon — you can stack the Amazon Prime Card Bonus on Canon (for 10% back total on select Canon RF cameras and lenses) with a $1000 instant savings on the EOS R3. The camera is listed for $4999.99, then you get a 10% Prime Card Bonus for putting the purchase on your Amazon Prime card, for a final price of $4499.99 (after the bonus).
Be sure to check Amazon’s list before purchasing — they can change the list without notice. Be sure to act fast, as they have removed items from the list within hours / days in the past!
