How long after a payment can I do a chargeback on my CC?

It seems the problem here I can use my CC for whatever, then months and months later do a charge back, even though I got what I originally paid for.

It sounds like the only defense would be to not ship the actual product (reward in this case) until the charge back grace period has elapsed.

Visa and MasterCard allow 2 months. But if you do a chargeback, the vendor can dispute it. Amex allows 4 months (atleast) and the vendor cannot dispute the charge.

So it seems like sites like kickstarter should only allow Visa and MasterCard, and people should not start sending rewards until > 2 months after payment has been received...
