It's the last rotating promotion on the Sears homepage. I will say there's some hassle involved. They'll call you or email you to call them to verify you're a human being, and the bonus e-card is only valid until the end of January.
There's a thread on SlickDeals that explains everything in...
For people looking at Sears for their chest freezer, they're currently doing a $10 free electronic gift card with each $50 gift card purchase. It takes a bit (up to 10 days) for the bonus e-card to come in, but if you can wait you can definitely save some money.
Cheers!
