Hello, I just published a Hub on how to embed your Amazon aStore into a Blogger blog. I went step by step and posted screen shots.
I didn't have instructions in there on how to create an aStore. I assumed the reader already knew that part. I might do a Hub on that later. Also, you can check to see if someone else has already done a Hub on it though. You can do a search for how to create an Amazon aStore in Hubs.
Anyway best wishes. If you want to check out my Hub, the URL address is below.
Oh, yeah. On Blogger, if you've activated the Amazon affiliate settings, you will see how to add Amazon products with your affiliate code already embedded when you make a new blog post. You have the option of adding the text link only, the image only, or adding both the text and the image.
I hope this helps.
