The Post Office Matched Credit Card
If zero interest on your purchases is important to you, this could be the Post Office card that suits you best, as it gives the longest interest free period of all the cards they offer – a whole 27 months.
You can also transfer a balance from an existing card onto the Matched card and enjoy 0% on that for 16 months, although you will be charged a transfer fee (2.98%) and you must make the transfer within three months of having the card.
After the introductory 0% period ends, the representative APR is 18.9% although the rate you get will depend on your own circumstances so it could go up to 22.9%.
