Sorry, this just isn't feasible. ASINs are by no means a globally unique and robust identifier. Even within the site itself, there are significant issues with duplicate products, abuse via ASIN swapping, etc. The author uses books, which at least have a standardized code via ISBN. Many other products, at best, might have a flavor of UPC/EAN and so on, but it is by no means required. Amazon doesn't even require it from those using its platform to sell or resell. This is to say nothing of the nightmare that would be mapping the many to many relationship of ASINs to local inventory. We also face a very similar issue where retailers 'accidentally' map that shiny new GPU to a dusty old brick that just happens to be named the same thing (but with a 10% discount..and free shipping!). How would we enforce honesty and fairness in such a proposal?
