This is a simple plan that is in fact working well for me at the moment, and the holiday shoppers haven't even started! Choose 2 products from Amazon affiliates that are not only relevant to your niche, but are top sellers that seem like they would make good gifts. (books seem to work well) Place 2 widgets in your blog sidebar using only the Amazon affiliate image's with the header "Great gift ideas" or something along those lines. Watch the sales come in if you have chosen your products wisely. This is very simple, but for the holiday season it might be worth making a little extra space in your sidebar. I have increased my sales significantly since placing these aff. link images about a week ago. I have blurred the product images below in order to preserve my niche, but you'll get the idea.
