How do you work out which fuel cards work in Castle Cary?
We take every forecourt in Castle Cary from the UK Government Fuel Finder scheme, look at its brand, and check it against where each card provider says its card is accepted. "Works at" means the provider says every site of that brand takes the card. "Possibly" means only some sites of that brand do, or the card's network includes independent sites.
Is a fixed weekly price or a pump price card better?
A fixed weekly price is easy to budget and can be below the average pump price. A pump price card with a discount lets you fill up at the widest choice of stations. If you mostly fill up in one town, pick the card that works at the forecourts you actually use.
