As an update to the question I asked in May 2008 [Blu-Ray DVDs in LOS?]:

When I was in Pantip Plaza last month Blu-Ray discs were available, but when I asked if they had them the vendor ran off to another spot and brought a total of about 25 back to show me. The two guys manning the stall knew that they were different but asked me to explain what the difference is.

They were in the regular blue plastic cases you'd see in a store instead of the cellophane sleeves you'd expect to see copied media packaged in. The price was Bt175, or around $5 US.

I only asked at the one stall just out of curiosity and didn't do any further searching. I suspect players and store-bought copies aren't widely available (if at all) because of the cost - just as some suggested when replying to the original thread.

Just FYI.
