With an Anytime card you can pay for your purchases in three instalments! The only catch is that it’s up to the retailer and they have the power over whether or not to accept your card.
Why? Your Anytime card is an immediate debit card so, in other words, you must always have sufficient funds to pay for your purchase, because you do not have the right to an overdraft.
This approach has many advantages, but it may dissuade the retailer from accepting it because of the risk of non-payment.
The most simple solution is therefore to ask them, making it clear that you have a debit and not a credit card.
