Sears offers a Shop Your Way Max 3-Month Membership
(formerly known as ShipVantage) for free
. That's tied with our expired mention from six days ago as the best trial offer we've seen for this program, which normally costs $79 annually. This program yields free shipping on millions of items with no minimum purchase required, discounted shipping upgrades, twice as many Shop Your Way Rewards points, and more.
Note that this will not automatically convert to a paid membership.
