Balance transfer and purchase credit card

Hi,

I am new to this so apologies if I am in the wrong place or this has been answered elsewhere.

I currently have a credit card with Tesco and my 0% interest is about to expire. I use the credit card solely for holidays; paying for flights and hotels so that I know it is secure and gives me time to pay it off.

I would like to complete a balance transfer to another credit card so that I can continue paying 0% interest and I have seen the best ones for the longest periods on MSE website.

However, I am unsure whether it is best to find a balance transfer and purchase credit card or whether to just complete a balance transfer and then open another credit card solely for purchases. I pay off a fairly large amount each month so it isn’t that I am in huge debt and need to pay it all off.

If anyone could offer any advice, or maybe even alternatives, it would be greatly appreciated.

Thank you

M
