Pay Prepaid on the Eight Listed Mattress Models
Open the Sleepwell payment page once with a prepaid payment method and once with your credit card's No Cost EMI option, and screenshot both totals before you place the order.
Sleepwell gives an extra discount for paying upfront, but only on eight mattresses: Ortho, Ortho Pro, Ortho Pro Latex, Ortho Pro Spring, Dual, Dual Pro, Ortho Genius Grid and Ortho Nirvana. On one of these, any payment that is not prepaid gives up that discount. On any other model there is no prepaid discount to lose.
If you are choosing between a listed model and one outside the list, take both to the payment page and compare the final totals there, not the prices on the product pages.
No Cost EMI works differently. The store takes the interest off the price upfront, and your bank adds the same interest back over the instalments, so your total stays at the listed price. It works only on credit cards from partner banks, and your card needs enough free limit for the amount the bank blocks at the start. Pick EMI to spread the cost, not to save money, and check whether the EMI total still includes the prepaid discount before you choose it.
