Have you been to Electric Mega store in Japan?
These stores stock household appliances such as TVs, PCs and refrigerators as well as cameras or game software in bulk, and sell them at low prices. Some stores deal in watches, toys and brand products. Typical examples are “Yodobashi Camera”, “Bic Camera” and “Yamada Denki”. So competition between these megastores will surely heat up. They offer low cost to compete each other. You can also get ‘points-card’ and reduce 10 to 20 % of the sales price. It is free to make this point card. Most these mega stores have English speaking staff. Lots of electronics are very unique and colorful. They have so many functions you never realized. I myself like to find gadget. I also like to find decoration for cellphone.
You may be able to spend whole day there. For example…
Colorful carry-along electric tooth brush! They are not only colorful, so many functions on it!
This is green tea espresso machine! You may able to have perfect green tea!
It is a speaker and you put on some object (e.g. table), it will send vibration to the object (table) , object (table) become the speaker!
