just phoned HMV Heeren earlier on about this & stock for both Japan press/CD only editions of the singles already came last night but at the moment they're still processing the stock so as such , they weren't able to give me the prices for both singles yet
will be heading there later on in the afternoon as the staff over the phone said it will be ready after 2pm
EDIT -
the price for both editions's
S$24.95 each
