WC: Shipping add-ons
We'd like the ability to add something like "Saturday delivery" as an optional extra for shipping, which would be charged at something like £25 extra, and without the need to add a whole new table rate of shipping costs.
So a way to add checkboxes on the shipping section to buy 'shipping add-ons'.
We've implemented this on a site but with some core hacking, so would like to have it built-in!
