You mean I can only have one or the other? The tax refund is only 5%, but the points collected can more than 10%.
Quite hard to compare prices from here in Singapore, Map does not seem to list the prices openly, maybe have to visit a few shops every day and night. Will be staying super near Map. Is Fujiya still at that place that is one JR station away from Shinjuku?
Ah, then it is still there, Nakano station, must remember.
the points are only useful if you are a frequent customer, for tourist the tax rebate is good enough already. you can't have the tax rebate and earn points at the same time since the point system is a built in discount system itself. otherwise, go to smaller shops like Map Camera and Fujiya Camera, the latter's prices are much more competitive, easily 10% lower than the big 3, but i don't think they have tax rebate.
Just noticed one thing, the prices between Yodobashi and Bic looks the same!
