Applying is that simple. If approved and you accept, you’ll have a credit limit added to your PayPal account ready to use immediately. Plus, you’ll automatically get 0% interest for 4 months on all your purchases of £99 or more.*
*Subject to status. Terms and conditions apply. UK residents only. The minimum payment due still applies to 0% offer balances. Any remaining balance due after the 4-month promotional period or any transactions under £99 will be charged interest at 21.9% p.a. (variable). In order to maintain the 0% offer, you need to keep up monthly repayments and stay within your credit limit.
