Testing whether a bigger reward later beats a discount now
Tata 1mg · Cashback3 min read
A click test with a select group of users gave a positive read on cashback over an upfront discount. Building it meant months of infrastructure work, so we shelved it for later.
Numbers shown are from the design file, not from the test
Every order at Tata 1mg already came with a discount, applied up front. The retention question was simple: what if we gave a bigger reward, but later, as cashback on the next order? A reward you can only spend on your next order gives you a reason to come back.
Cashback would live in 1mgCash, a wallet inside the app. You earn it on one order and redeem it on the next.
The sheet opens when someone taps “Confirm and pay” in the cart. It sets the two options side by side on the same order, so the person sees what each one is worth before choosing. Tap a tab to switch the choice.
"Save ₹181 more by converting your discounts to 1mgCash" opens the sheet with the difference, in rupees.
Use my discounts: pay ₹2266 and save ₹514. The other option comes next to it, so the choice is a comparison and not a promise.
"Redeem 1mgCash completely on your next order" says where the reward goes and when.
"Confirm and pay ₹2266" keeps the usual checkout. "Skip" is always there.
Get 1mgCash: pay ₹2780 and receive ₹695 in 1mgCash, against ₹514 of discount. That is the extra ₹181.
The reward only works on a return visit, which is the point of the idea.
"Pay ₹2780 and get 1mgCash" changes with the selection, so people always see what they are agreeing to.
The sheet only appears when it makes sense: for logged-in users with an address, on carts that are only prescription medicines, and when the discount is under 20%. It comes before the prescription and delivery-time sheets, so it never interrupts them.
We first designed it around Neucoins, the wallet and loyalty coin of Tata Digital as a whole. Then we saw the risk. If the reward was in Neucoins, people could spend it at other Tata stores like Croma or BigBasket. They would leave 1mg for it, and 1mg would pay for a reward that sent the customer elsewhere.
So the reward became 1mgCash, which only works inside 1mg. The reward now brings the person back to the same place.
I tried three places to put the choice.

We chose the sheet. It was the easiest to build, and we wanted to test fast.
We ran a click test with a select group, to see how people felt about cashback against a discount now. The sheet in the test ends with a “Coming Soon” message and takes the person on to normal checkout.
The reaction was positive. But a wallet that pays out on one order and redeems on the next needs a major change to the infrastructure behind it, and that meant many months of development. The team shelved it for later. I don’t have numbers from the test, so I won’t quote any.
A click test can tell you whether an idea is wanted before anyone builds it. The build would have taken months. We learned the people side first, and the sheet is designed and ready for when the infrastructure is.
