No payment Information Required and Free Shipping Method DON'T work on one site but work on another!
I run an e-commerce website which has 3 sub domains. On each domain i have set up both no payment information required (mainly for testing, but is also used by some of my colleagues when out on site) and free shipping, this allows customers to pick up from our locations instead of paying for shipping.
I have these set up exactly the same on one site as i do the other. But on Site A it works, and on site B it doesn't.
