Hi Sue, Was alerted by a friend to another reusable tote bag promo. this one is from Coles Garlic Bread products. Tote bag is available only WSL. I'm assuming Proof of Purchase is UPC code from product. But you also need to submit the original CRT(s) Three Proof of Purchase & original CRT(s) required for EACH tote bag ordered.
