Amazon derives many of its sales (around 40% in 2008) from third-party sellers who sell products on Amazon. Associates receive a commission for referring customers to Amazon by placing links to Amazon on their websites if the referral results in a sale. Worldwide, Amazon has "over 900,000 members" in its affiliate programs. In the middle of 2014, the Amazon Affiliate Program is used by 1.2% of all websites and it is the second most popular advertising network after Google Ads. It is frequently used by websites and non-profits to provide a way for supporters to earn them a commission. Amazon reported over 1.3 million sellers sold products through Amazon's websites in 2007. Unlike eBay, Amazon sellers do not have to maintain separate payment accounts; all payments are handled by Amazon.
You can save even more money by shopping with discounted gift cards. “Companies like CardCash and Raise offer gift cards up to fifty percent off, so a one-hundred-dollar gift card could be purchased for only fifty dollars,” says Conway of Slickdeals. “Some gift cards to popular merchants may be a lesser savings, but every dollar counts, especially if you're making a larger purchase.”
