Oh yes, when in Asia, take some time to haggle over the notes. The BEK inserts were HK$250 each originally, but since I bought the whole set, they lowered the price to HK$1,000 after I said I would only offer them HK$750.
I saw a 1937 $1,000 there too, but it was close to HK$30,000 for a VF+ note, a bit out of my range.
