i wasn't trying to be a jerk or anything, but this sale was posted twice (in this week's sale threads)
also, there have been threads where users have come across 16x TY, but finding them is not very consistent...they ARE out there though.your best bet is to look for a whit octagonal spacer and MIJ on the package (but it's not a aure thing like the 8x)
still, the only way to find out what your store has is to go there.
all of the stores in my area carry the sony branded TYs, but other people in other areas have different experiences. This varies so much that no one can tell you what your store will have.
