Refinish old furniture from thrift stores, yard sales, or online ads. Sand down the furniture to smooth out the surfaces and buff off some of the old paint or stain. If you want to restain it, use a lacquer or paint thinner to remove the stain. Then, re-stain the piece. If you plan to repaint it, apply a primer and let it dry. Next, apply at least 2 coats of paint, letting each coat dry for at least 24 hours. If necessary, add new hardware to finish the piece.
Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
If you're not technically inclined at all, register your domain wherever you set up your hosting. Otherwise, you can save a few dollars by choosing a lower-cost provider. This is not a big deal for one or two sites, but it can be for 10 or 20. GoDaddy is a good option because it offers great domain management tools and at a low cost annually. One of the least expensive and reputable in the market is 1&1. Prices start at the low end of the spectrum for the first year with increases, sometimes significant for each subsequent year, depending on what plan you choose.
I recognize that the list above is short; however, that’s because Amazon affiliate marketing really doesn’t require a specialized theme in order for it to work well (unless it’s one of the unique cases noted in the themes above). Instead, you’re better off using WooCommerce if you want to build a full affiliate store or simply stick to the WordPress theme you currently have and add affiliate plugins to the mix.
