I've just received an email from Next about changes to their credit agreement. Looks like they are going to start charging interest on ordered goods from the day after you collect them from store (or they think you'll collect them) or the day after they are delivered.
"We’ve added wording to make clear that, where you have placed an order for delivery to a Next store, we’ll begin to charge interest on that item either from the day after it’s collected from the store or from the day after we expect the order to be available for collection, whichever is sooner."
You haven't even got time to try them on and take them back before you're charged interest! I'm terrible for not usually reading these sorts of emails but did this time.
Edit - I just phoned Next and the only way to be able to place online orders and avoid the interest charges it to make sure you have a cash-only account so you can pay for items at time of placing the order.
