I haven't received any offers from Big W for months however I am receiving constant reminders from EDR via email and on the bottom of every Woolies docket to remember to use the voucher book they sent me. Given that none of the bonus points for $spend are anywhere close to my usual (relatively low) spend at Woolworths, none of them will get used and the "percentage off" offers when you spend $X in a certain department don't match any of my spending habits either, so their data mining seems to be pretty off as far as I'm concerned! 20% off when you spend $15 at the bakery? The most I EVER spend is about $3-4 for a bag of bread rolls. 15% off when you spend $25 at the deli? I rarely ever buy anything at the deli except for the occasional roast chook, and even then only when they're marked down , or some chicken fillets, which never cost more than $10.
