Coming soon, you'll have to buy the latest version of SCA/SCS or you will lose the ability to offer ANY kind of promotion on your web site. This includes free shipping, % off coupon codes, buy X get Y, basically all promotion types. The only way to create a promotion once NS rolls out this change will be to use the suitepromotions app, which doesn’t work with site builder or even early versions of SCA.

This has been announced but there is no date yet. Let your account manager know if you feel that arbitrarily removing the most basic functionality in an attempt to force ‘upgrades’ is unacceptable.
