The only ones i have come across are the newsagents at Warringah Mall in Brookvale and a couple of shops in Campbelltown, one that sells ciggies and that sort of stuff, wouldn't trust them though as they wouldn't open a new box for me and had quite a few inserts for sale as singles under the counter so probably been doing a bit of case searching. The other place is a little stall called Cards R Us in the Spotlight Arcade, run by a guy called Clayton who seems OK.
