I received a similar offer - $70 per week for $20. Might make it, might not.
Mind you, would have been nice to have received it earlier, seeing as the promotion started today - I checked my emails this morning before heading off to do my shopping (if you don't shop the catalogue specials on the Wednesday, you often miss out with our local Woolies!) and this email offer wasn't there then, so it's a bit annoying to receive it AFTER I've done a shop that would have counted towards the total.
