I have 3 different credit cards from different banks. I want to consolidate these into one account so I have only one payment. I don't want a loan or anything, just merge the 3 card debts into one and pay that off.

Is it best to merge these onto one of the existing 3 (the one with the best deal) or get a new card entirely.

I will be cutting up any cards that are no longer used.

Thank you
P.
