I've made several calls to Amazon over the past year and the bottom line is this. This has to be a bug on hubpages. I know from the times I have previously written about this that it does happen to other writers.
When I try and link to various ebooks on Amazon, a capsule comes up and says that the product has no price and cannot be sold. This is despite the fact that there is very much a price attached to it.
I'm going to give you asin numbers so that you can check this out for yourself
SA: this has been happening on and off for quite sometime and it does appear to be an HP related issue as well as putting the ISIN number and nothing showing up when you know that the product does exists because you just bought one!
I just discovered something else. It's intermittent. If you keep trying, the link eventually comes. Also, it seems to be the ones that start with a B - although that could just have been a coincidence.
