Buying points seems a good idea - at least you'll use the product!
Anyone in oz that can use a woolworths temporary card on your behalf if you don't have one already? From memory I think I got mine from the grocery store then linked it online. Had the plastic one to come sent to friends address. Would be easy enough for someone to walk in and do, then take pics of the pamphlet to email to you to takeover the linking online, then they keep the card for 18 monthly purchase. Can't remember if there's a minimum purchase - maybe $30? They just need to swipe your card through on ONE of their grocery shops in 18 months, you don't actually need to shell out $$ for it.

I've seen other threads with people in the same situation if you search this forum with a number of replies/solutions.
