My two local supermarkets now have a Uk food section in them.
I can now but PG tips, weetabix, marmite, colemans mustard, Alpen, Ambrosia custard just to name a few...
Also the Sweet shop nearby has a Uk section too - Yorkie Bars, curly wurlys, Maynards wine gums and Thorntons choc bars...
DH (Brit) is quite excited about this but is showing restraint as it's all a bit expensive.
Not bad considering I'm in Melbourne...
