if you are giving away the points and you are in osaka.. ill help you out
and yeah "KAKAKU.com" is one of the best site to compare prices.
I recently bought a digital camera(
http://www.fujifilm.com/products/dig...800/index.html) in yodobashi for 20000.00 yen, luckily they have a special points promo that day. Instead of the usual 10-15% , I got 25% worth of points thats about 5000yen. Not a bad deal actually.
Actually tyler, if you are staying long in Japan, get the point card in yodobashi camera. Its free and you can use your accumulated points to buy other stuff in the store. And also the store employs English speaking Japanese staff, so you can always ask for them.
