If you don't deliver before 4 weeks, chances are all the credit card pre-authorizations would be void anyways. With Stripe, it's even shorter.

Unless you plan on capturing the funds at order time instead of shipment time?

Thanks for the heads up on this.

Hey from where are you shipping this from ?? I mean r manufacturing ??

We have a factory in San Francisco which is where we will make and ship these kits from.
