Free Shoprunner for Amex

Not too long ago I got an email from American Express offering a Free ShopRunner account.    If you have an Amex card then you may have gotten the same email.   As a benefit of Amex they are giving free Shoprunner.

If you have an Amex card then You can sign up here.

Shoprunner offers free 2 day shipping on a variety of online stores

I don't see any strings attached and it doesn't appear to be a limited trial or but an indefinite benefit for Amex members.
