I'm having this same problem - not always, just on some products. For instance, I've written a hub on the new Playstation Vita - it is available to pre-order in 2 iterations on Amazon, but when I copy and paste OR type in the ASIN, I get "no results found".
On other hubs they link straight away, it's just some. Neither the ASIN nor the URL work.
The easiest way to do it is to open a new browser page, go to amazon, type your search in THERE, and then copy/paste the link onto your Hub. Easy AND faster (my opinion).
I am having the same problem with pasting - I feel like I spend more time trying to get this right than hubbing - very frustrating!
I appreaciate the suggestion, but I actually tried that first (before going to the Amazon Capsule)... and it didn't work either. The only results displayed on the Hub page were "No Results Found"!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
