I went back to that Singapore store the next day to see if they had the combiners in as well (I was hoping they were both out at the same time like BBTS should be), but couldn't find any... and the staff member had trouble understanding what I was asking about too.
I was there a couple weeks ago, but didn't make much mention of it beforehand. I posted up a reservations topic in the saleyard... I just didn't want the general public to know I was out of the country for a week.
