And what is this limit on Woolworths dollars earned per week? Hope that is for a specific promotion and not general shopping.
The $10 limit referred to in a previous post is for the "Double Woolworths Dollars" promotion, where if you earn WW$ during the promotional period (can't remember the exact dates, I think it was a 4-week period ending around 13th December?), you will receive double those dollars , but only up to a total of $10. I think the "double dollars" credit is supposed to be put on the account the week after the promotion finishes.
I don't think there's a limit to the amount of WW$ you can earn from general shopping.
