where you pre-order from?
I ordered mine from 11street's Game Hypermart, didn't get any request for extra cash
if you ordered from those online shopping sites like Lazada, or 11street, the seller aren't suppose to increase price after they put it up
if they asked you directly for extra cash, it's a direct violation of the T&C of sites, which will incur heavy penalty to them by those sites
likewise if they cancel your order from their side, also will get penalty, most they'll just contact you to pay more or ask you to cancel your order from your side, which is what they are doing now.
IMO, you shouldn't pay the extra amount, currency fluctuation is plain BS, few months ago the USD exchange rate is already pretty high. Tell them they should honor the published price, do that or you'll report this to the online shopping site they used.
I just received call from gamehypermart, i made my order from 11street for both nes classic and controller, they asked me to pay extra RM85. I just asked them email me the details first. I still don't know what to do. I think you will receive their call soon.
I also realized I have pre order the famicom mini from them through gemfive as well. ==
