Avios Barclaycard is allowing a balance transfer, but how do I separate paying purchases in full?

If you have purchases and a BT on a card you will pay interest even if you pay the purchases off in full. 

Not true if you play it right. 🙋👍

You have to wait till you get your monthly statement. Total all the purchases on that statement & then pay them off, them add on the amount to cover the balance transfer. 
So it is best not to do this the 1st month after balance transfer, as you then have a figure to work from. 

Is that not the chase with some cards i.e Barclaycard as one of the posts above said. Others will charge interest if all the balance is not cleared. I have a zero coop deal running and have some subscriptions being paid from that account as I have not bothered to move. I am charged interest on the subscriptions (pennies) even though I make an extra payment to clear the subscriptions
