Latest reviews, United Kingdom Google Play.
The points cannot be used at Lulu which was disappointing, and the coupons only apply to specific items. Instead of getting a QR 26 discount, I only got a QR 6 discount on Noun. This makes putting the bottles in the machine a waste of time, as I didn’t collect 300 points just to get a discount of only QR 6. Maybe in other apps the discount works better but for noun it is disappointing.
very helpful 🙂
i love the concept of the apps .. it help for nature and for people also . its really helpful , the issue is i need to travel from Umm Al Quwain to Ajman , I hope they will put machine also in Umm Al Quwain.
Good
Nice app
I really wanted to use the app since I know I spend so much on cans, but for some reason it won't send me a code either via number or telegram. Why should I waste my cans when I could use it here? please help!
