Amazon.com: one piece
Look for a tv listing here:
Listings Setup International | TVGuide.com
Or here if you live in the US (I think)
Listings Setup | TVGuide.com
As for subtitled episodes you can legally find on the net, I have not found one after a few minutes of googling.
If you are requesting for websites that offer to watch these episodes for free on the internet...
Don't request or post links to licensed materials, illegal content or pornography.
Closing due to the above stated fact.
If someone truly find a place to watch One Piece legally through streaming, please PM me and I will re-open this thread and let the information be known.
