I wouldn't buy a new domain for each "item" you want to market. We recommend people build websites around "niches" where there are a few good affiliate products to promote.
Eg, instead of building an affiliate site around the product "Affilorama", you build a niche site around the topic of "Affiliate marketing" or "making money online" or "home based business ideas" or "building websites", and then you promote Affilorama alongside a number of other related products. (Eg, a web hosting company, a SEO tool, web design software, WordPress themes, etc)
Instead of building a site around Super Tummy Trimmer 2000, you could build a site around weight loss in general, and promote weight loss products, exercise and diet guidebooks, gym equipment, gym memberships (?), etc.
Building a fresh site in each niche has a few benefits:
1) You have the chance to make more than one sale to a visitor.
2) Your site appears more relevant for your topic because you have more than one page of content on that topic. It appears to be higher quality from a search engine perspective.
3) You're not putting all your eggs in one basket, and if the one product you're promoting starts to tank... you have a few others to fall back on.
4) Your site makes more sense to a visitor, and you develop a distinct brand and character. Think about it this way: if you're a physical store trying to sell car stereos, you're more likely to succeed if you specialise in car stereos, or at least car parts. If you're trying to sell car stereos from a junk shop selling homewares, pet supplies, candy and used books at the same time... people are less likely to see you as an authority on the topic of car stereos.
5) If at any point in the future you want to sell off your site... MUCH easier if it's a separate domain!
Depending on how you're planning to get traffic to your site, in most instances affiliate sites these days need to be more than just single "thin" sites with little content. In most cases you need quite a bit of content backing you up to prove your "quality". And if you're building content, it helps if that content is roughly on a similar topic.
There are always examples of sites that will defy this logic, but it's a safer approach.
