Yes, that is no problem, you can choose to do this through Divide Buy. With this option, you would spread the cost of your order easily in monthly installments between 2 and 12 months and every order is entirely interest-free, no matter the basket value or term length.
With this option, you may be required to pay a deposit and first installment at the time of purchase. You can then simply log into your account and make an additional payment. You will have the option to either reduce the amount of your monthly payments or the length of the finance agreement. As it is 0% interest you will also not be charged any extra costs.
