@David It can be used to get someone who missed the deadline onboard (but, again, it will only be up for a few days).
Never mind. I think this page answers my question:
Re: "Also, we wanted to let you know that for a short time we will leave open a way to pledge via our website and Paypal. Again this will only be for a short time, in case anyone has trouble with their Amazon payments, or for those $1 backers that didn't make it on time to up their pledge (we've had a few requests already)."
Could I have a bit of clarification on this. Is this offer just for people who have the wrong pledge level, or can it also be used to get someone who missed the deadline onboard?
