I run a small, entertainment niche blog. When I search for stuff, I frequently see Google's suggested search terms relate to merchandise for this particular niche - mostly t-shirts, but also toys, accessories etc. A related domain name is available that I could use to build a site that's focussed purely on selling this merchandise.

I already have an Amazon affiliates account and I thought about creating some kind of site where I basically just create some kind of an online store that features the Amazon products and then links through to them (not sure if that makes sense?) - has anyone done this kind of thing with any success?

I've had some experience in creating review-style affiliate sites, writing 1,000 reviews of a product and linking through to Amazon, but t-shirts aren't really the kind of thing that warrants a review.

I guess my most basic question then is, without writing reviews, what's the best way to create an affiliate site for entertainment merchandise?
