Tim Tams are available here in South Africa from the local supermarket. Priced at around US$1.35 they aren't too expensive and are really delicious. Having said that I try not to buy them, because if I eat one, I usually ended up eating the whole packet!
For your information Tim Tams are Australia’s favourite chocolate biscuit. Around 30 million packs are sold each year - that’s nearly 300 million biscuits, or two packs for every Australian.
There are eight delicious varieties of Tim Tams: Original, Chewy Caramel, Mocha, Double Coat and Classic Dark Chocolate, Special Edition Tim Tam Hazelnut, Limited Edition White Chocolate and new Special Edition Chewy Choc Fudge.
