On the main product page there may be a section just below the product features called “Special Offers and Product Promotions.” If available, you can find some special offers and savings, like a free mp3 download with your purchase. Right now Amazon is offering 2% back in rewards on select camera products (Update: Promotion no longer offered).
When you’re buying expensive camera gear, 2% back sure adds up to a lot of savings! Note that this rewards offer does not require you to have an Amazon Rewards card. (But if you’re buying a lot of gear, I’d definitely recommend picking up an Amazon Rewards Card.) With the 2% back offer, you’ll receive an email notification 35 days after your product is shipped, to inform you that your rewards have been applied to your account, which can then be used on any item that is shipped from and sold by Amazon.com.
