– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.

The great thing is, you don't have to deliver a generic email because you do actually know a few things about your visitor and what they want.

We hope our personal recommendation was a winner, but if not click here to read our full guide to buying the right gas grill.”

Amazon offers a service called Fulfillment by Amazon (FBA), which can be extremely useful for arbitrage sellers, or others selling their own products. If you opt for FBA, Amazon will store, pick, pack and deliver your products. That means you can scale your arbitrage business quickly as you don’t have to store products in your own home or waste time with postage.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.[citation needed]
