I sent a feedback through to shop a docket today about a merchant that wouldn't accept a printed coupon from the website. (as my local Coles has been printing receipts with a blank reverse side).
Got a reply from the great people at shop a docket that they would talk to the store but they also advised me that Coles no longer uses shop a docket. My local store stopped a few weeks ago.
So shop a docket now does: Woolworths, Kmart, Target and Big W.
Thought I would share as I couldn't find any information about this online.
Eh, if I want to I just check the website, redeem from a smartphone
