If I did the deal @ amazon, can I do it again here?
Yes you can. The rebate form has a unique rebate ID number. As long as the rebate ID if different, the rebates are considered different.
I have claimed multiple rebates on the Canon Pro-100 + 13 x 19 deals.
Amazon Shoppers: Amazon's 3rd party sellers have inferior buyer return policies so watch out incase something goes wrong with your purchase.
Don't be an easy spender, be a frugal deal seeker. Having patience is a big part of being a great slick dealer.
