Update: Goodbye Kiss with English Subs Still Available

After a bit of homework, I've been able to find and order a DVD of The Goodbye Kiss with English subs. The version I found is the Thai DVD reviewed on Film Threat. The vendor is HKFlix and the listing is under the film's Italian name.

I placed my order, it went through easily and HKFlix is considered to be reputable. The DVD was cheap and so was shipping.

One caveat for the U.S.: You need a region-free DVD player with PAL conversion to play it. Many are available on the cheap if you don't have one. Chinatown is always a good place to look.
