If you have bought something from WW, while always scanning your EDR/WWR card in the past, they seem to bring it out again for you, or I to buy again for bonus points accrual.
Long "jumbo" bread rolls for eg, about 6 or 8 weeks ago, I decided to start buying these, as they accrued bonus EDR/WWR points, now they come every few weeks.
My offer ends on every Tuesday, so that bread roll offer might not appear every week, but will come back next next week.
As for buying things, then ignoring, and then not scanning your EDR/WWR card, I don't think WW knows this, ie, you have bought this in the past, and then now buy it, but not scan your EDR./WWR card.
All your receipt will read is "you could have earnt 1000/xx_/xx points", but that system wouldn't know you are an EDR/WWR card holder/member.
Trick it buy it, and then stop buying said item, but always scan your EDR/WWR card, and I mean always, and also ask the guy/girl if the card details have appeared.
This way their system knows who you are, and the fact you have not bought that item for a while, it will come back.
I am ignoring the "toys" from BigW offers, as I have not kids/(puppies), but the EDR/WWR section keeps sending me offers for buying toys from BigW.
Edit: can't we warble like magpies at night?
