If you're planning on mailing out physical rewards to your supporters, you'll need to enable shipping options! There are a couple of options here depending on what you require.

If all you need are mailing addresses, and not extra fees from your supporters, all you need to do is enable 'Free Shipping' on each of the relevant rewards.

In your Rewards editor, scroll down to 'Shipping' & click 'See Options'
​

Click 'Require Shipping Options for this Reward' & select 'Free Shipping'
​

Make sure you hit 'Save'.

Your other option is to charge shipping fees on top of the supporter's pledge amount. This will add your nominated cost on, and also require supporters to add their nominated mailing address.

In your Rewards editor, scroll down to 'Shipping' & click 'See Options'
​

Click 'Require Shipping Options for this Reward' & select 'Collect Extra Shipping Fees'
Add as many options/prices as you desire!
​

*Remember you'll need to add shipping options to every reward that requires shipping!
