HalfSize.me globally checks for availability and prices of a given ASIN. The system was built by some audiophile music lovers hunting for rare discs. After Amazon recently pulled the plug on most of the existing price tracker websites (by blocking access to their API), HalfSize.me was created as a replacement to deliver realtime pricing information. It was mostly built for internal use, but feel free to give it a try. If people like it, shipping cost calculations,
currency conversion and other languages can be added to the site.
HalfSize.me covers any Amazon retail website that sells physical goods and allows international shipments from its Marketplace. As above, these are currently .COM, .CA, .CO.UK, .DE, .ES, .FR, .IT and .CO.JP - with more to come. Any new country will be added immediately.
Excluded sites: .COM.AU and .COM.MX are currently only selling virtual goods (e.g. Kindle content). On .CN and .IN, Marketplace vendors apparently cannot ship abroad. .AT is a rebranded mirror of .DE.
"Amazon has separate retail websites for United States, United Kingdom, France, Canada, Germany, Italy, Spain, Australia, Brazil, Japan, China, India and Mexico, with sites for Sri Lanka and South East Asian countries coming soon. In 2011, Amazon had professed an intention to launch its websites in Poland, Netherlands, and Sweden, as well. An Austrian website operates as part of the German website."
Chances are that you are using HalfSize.me for hunting rare or niche market music releases, e.g. high resolution audio media like SACDs, DVD-As, HFPA or else. In that case, checking out these great web sites and forums for audiophiles is highly recommended (in alphabetical order):
