Im not actively collecting Lego for a few years now since I have no room for my "city" now. But back in the years I did, I just go retail. Ebay was an option but you have to be very choosy and quick coz Lego prices don't drop.
Too bad about BBTS, would've been great with them coz of the POL system they have,
