It's not a good idea.
If anything goes wrong, you would only be eligible for the refund of your first payment, not the two or three that make up the total.
You can deposit money into your Paypal account to make a PP balance and pay once in full from that.
Can you amalgamate all the credit card balances onto one card and then pay from that?
And finally, are you sure you can afford it? When your next payday rolls around, it is likely something very similar or even identical will be available.
