Sydney communters - This is a good way of combining two deals to top up your OPAL Card.
Simply top up $100 at Woolworths and get bonus $10 for next shop (top up the extra $10 immediately if you want)
If on ING/ME bank 5%, don't forget to pay in $1 cash, then rest on pay pass for 5% discount.
If Entertainment book member, get 7.5% discount buying Big W e-gift card which can be used in-store at Woolworths. Might take a couple of hours to come through to your e-mail.
Opal top ups is definitely the best way to take advantage of any woolies deals (for commuters)… unless there's a Amex shop small promotion around which definitely trumps this. But there aren't, so up vote from me.
If on ING/MEBank though just top up 2x $50 ;) (or $60 & $40 to be more subtle).
Oh, also don't forget about Dan Murphy gift cards, or the e-Gift cards off groupon that were here with an approx 9.14% total discount (combining the 5% off from groupon + cashrewards). They would be better than the entertainment book discount you've mentioned.
