This afternoon they had frozen mangosteen from Thailand at the San Gabriel Super Store (San Gabriel & Valley Blvd.).
$2.99 a bag and looked like about 12-15 of them in a net bag. They were frozen rock hard like they were just put out in the fresh fruit section right next to the dragon eyes. I didn't buy them because I wasn't on my way home right away.
I was having lunch at the Yum Cha Cafe.
