50% back?

KeY went shopping today at Centrepoint - and we found out they had this UOB Lady's Card Promotion. Spend $100 on the card (in 3 or less receipts, same day, blah blah) and you get an instant win lucky dip (among other things) and KeY got back a $50 Aldo voucher which seems to have almost no strings attached.. pretty productive shopping, lol...
