A couple of days ago Blog Kindle reported about Amazon’s launch in Spain. The site went live already and you can check it at the address https://go.redirectingat.com?id=28128X862189&xs=1&url=http://www.amazon.es/.
Kindle Store is not running in the Spanish-localized site, but according to Blog Kindle:
While the service will cover only physical goods at the time the store opens, it will expand to digital content including a Spanish Kindle Store before the end of the year.
For the time being you can browse for Spanish titles in Kindle Store US. There are as much as 11,000 Spanish-language books there, but it’s not easy to find them. Here are some tips how to do it.
It looks like a second non-English Kindle Store, following Germany, will be opened in France.
