Hi Shoukei,
You can post contents about the episode reviews, informations like the characters' profile or exclusive information you found anywhere.
Since you are affiliate for rightstuf.com and animenation.com, do they provide any banner or picture ad for you to put in your blog? If they do, just post the banner in your blog.
You can also anchor your affiliate link in your post and your signature.
Give a thorough comment on others blog about their post. Try to avoid comments like "good job", "I think you are right". If you think they are right, try explain why. Your readers will be more likely to clink on your link because it looks like you really share what you think.
I think you should combine your blog post with the anime information and the anime product. This means that you talk about the anime product after a few posts about the anime. And again you can anchor your affiliate link at your signature for every post.
And when you are talking about the product, highlight why they should buy the product. Maybe for collection or for easy viewing. If your merchants provide email message, you can get inspiration from there and write your own short post about the benefits of getting the product.
By the way, you can also join anime forums to get information and maybe how to promote the product.
I hope that helps.
