Getting the EOS-M3 is a sure thing for me.
On Yodobashi Camera website (electronics retail giant here in Japan), the M3 EVF kit is being advertised for ￥64,580 which includes tax. The body-only is advertised as ￥61,340.
I am also based in Japan, and I never understood why on earth people shop in Yodobashi\ Bicamera at all???
Their points system is an absolute rip off!! Just check the Amazon Japan prices, and you will see Yodo and Bic just add to that price and then pretend you gain something by offering you points with money you paid extra!!! (CFR. The prices you mentioned for the eos m3 and eos m3 plus finder set....)
Take my advice and just stick to Amazon in Japan!!!!!!
Thanks for the suggestion, but I don't actually buy anything from Yodobashi. I realized years ago that their point system was just an elaborate marketing scam. I only mentioned them because the little camera store I buy my gear from doesn't have any information about it online yet. I just used Yodobashi as a point of reference. The place I buy it from will definitely be cheaper. Thanks though. I'll keep an eye on Amazon to see if it beats the store I usually buy at.
