Dmart ready prices are higher than the dmart store, For the same store for delivery, I never able to beat the offline prices on many of the products when compared to online with 5% cashback + 29 rs delivery
Example, Tata Tea gold was sold at 475 online
Tata Tea gold at 445/450 at store
On offline
When we swap 1%(sbi cashback), 1.5% (tata neu) will be extra on top of the offline price. Currently I have only these two cards and not needed to any third just for grocery
Try at yourself while visiting store if nearby. Mine one is just 2 km away
