With your Freedom, you can activate the Blueprint Full Pay feature. If you do this, charges you make (purchases) in the ACTIVATED Blueprint categories you choose will not accrue interest any interest if you pay them in full by the due date on the first statement they appear on even if you are carrying a balance (purchase, transfer, or otherwise). You will have a new "Blueprint Payment Due" amount every statement that includes your total Blueprint Full Pay charges and your minimum payment due for the rest of your account balance. Paying the Blueprint Payment Due will satisfy your minimum payment requirement.
I know this because I ran into the same issue with a BT on my Freedom. In my case, multiple reps told me no interest would be charged on purchases if I pay them by due date (just like you thought as well). When that didn't happen, a supervisor reviewed the tapes, credited the interest charges due to their error in explanation, and explained this Blueprint feature. I then used the feature with no issues for months.
Let me know if you have any questions!
