Got mines a few days ago
This was the text message-
Mr X , your Woolies card Black Friday cash-back voucher is available on the app. Don't have the Woolies app, download it from your phone's app store. Ts&Cs apply. Voucher is redeemable in store only. It pays to pay with your Woolies card. FSP/NCRCP49.
Edit : mines is a R300 voucher. Don't know how much I needed to spend but I know I used a buy 3 , pay for 2 for the qualifying transaction.
Just check perhaps in the app.
Also got a few discount / cash back vouchers to encourage spend.
They are going to possibly regret it

- really hoping I can stack them all in one purchase as a i also have a 10% birthday discount that is expiring soo.
