Buy a $100 eBay gift Card, Get 2000 Bonus Rewards Points @ Woolworths. Enjoy :)
Edit: Some users have reported that the gift cards may not work on Car / Vehicle Parts. If you intend to purchase parts with the gift card, contact eBay before purchasing the gift card.
What? I think we got some wires crossed here.
Transaction 1: I bought 10x $100 cards for $1000, which gave me $100 credit.
Transaction 2: I bought 2x $50 cards, using my $100 credit.
Then I changed stores and repeated the process.
If there is a limit, it must be a 10 card limit per transaction.
PS: For the salty downvoter(s), store 1 had another 10 cards on the shelf and store 2 had another 14 on the shelf when I left. I could have cleaned out the first store, but I didn't.
