Hi Debbie....welcome to the Forum
Yes, this is the right place for this post.
I suppose the best way to buy breakdown cover is to first weigh up what you need...e.g. multicar, european cover, personal cover, homestart, etc.
If you don't need any other options than roadside cover and being towed to a garage within 10 miles of where you broke down then that would be the cheapest method.
After that, you can bolt on various options and then it becomes quite expensive.
You get what you pay for, as the old saying goes!
