I wish all reviews from amazon sites (US, UK, etc) are merged, so I don't have to go to each sites when I read reviews, particularly for music review.
A single nation separated by TLDs.
(don't forget ca, au, nz, za, in, si, bz, etc.)
I wish they were merged period. I wanted a book that was on the UK version but not in the US version. It took me a while to figure out amazon wasn't amazon, it was amazon other. So I didn't get the book because I didn't want to sign up again.
Good heavens no, I don't want them merged. Amazon UK sells lots of stuff that Amazon US doesn't sell. I want to keep the extra choice, variety and availability.
