ShopRunner is a similar service to Amazon Prime in which you can shop for millions of products and receive unlimited 2-day shopping and free return shipping on any of those items. This membership is offered as a free benefit with your American Express Credit Card (at a $79 annual value) and if you have an Amex card but have yet to sign up for this free benefit, click here.
American Express just sent out an email notifying Shoprunner members that there is a change coming to their program. Effective on May 1, 2015, a minimum order size will be required at certain retailers in order for you to receive ShopRunner free shipping benefits. Specific changes to the program are not specified but you can learn more by reading the terms and conditions. This is not a significant change to the program and for those of you who have yet to sign up for this benefit, I strongly recommend you take advantage of this great perk for online shopping!
