PayPal credit is like a credit card, there is no plastic and this is a credit line, located next to your PayPal account, and you can use it for online purchases in Kwik Fit. You can use the 0% interest discount repeatedly: the 0% interest discount of PayPal Credit is better than the introductory discount. Every time you spend £99 or more, you will automatically get 0% interest for 4 months of purchases.
