I don't know PC's terms, but I strongly suggest reading the fine print very carefully. The promotional rate probably doesn't apply to new purchases, just the originally transferred balance, and that balance is probably reduced by all your payments, before it is applied to new purchases, so you pay full rate very soon.
Only one way to handle credit cards, imho. Pay in full every month so you don't incur interest. If you need to borrow, use a low interest source such as line of credit - your credit card is always the most expensive way to borrow.
