If you’ve never ordered anything using Amazon’s Subscribe & Save option, Amazon will give you $10 for free to use on your first order. Simply enter TRYSNS10 in the “Gift Cards & Promotional Codes” box during checkout. If you’re unfamiliar with Subscribe & Save, it’s a great way to save on everyday items. You add items to your subscription list and save 5% off the regular price. If you add 5 or more items, you’ll save 15% off the entire order. Once a month, Amazon ships out the items on your Subscribe & Save list. You can remove items from your list at anytime, even after just one order gets shipped. So you can subscribe to an item, get the free $10, and immediately cancel the subscription after your item ships. This offer is good through July 4th and you must be an Amazon Prime member.
