I've written up a guide that will allow you to save a large amount at Sears and Kmart. I have personally tested this multiple times without issue, and it involves no greyhat/blackhat methods. This works both online and in stores, although prices may be slightly higher in store.
The discounts attainable vary greatly depending on current promos they have as well as lifestyle (points for activities).
You can expect a minimum of 20% off list prices for many larger electronics, and well over 50% off in some cases for relatively small purchases like clothing. Many of the discounts come in the form of Shop Your Way points, which can be used for $ off your next Sears/kmart purchase (including other vendors selling on there), or lots of items on
SYW's websiteThere's ~$25 in one-time bonuses that come with the method used, so it will pay for itself the first time. Free 2-day shipping for 90 days is also included.
The guide costs $5. If you have some reputation I'll send first.
This does not work on the international Sears/Kmart website. It is possible to pay with Bitcoin through Gyft, but you will miss out on some of the one-time bonuses and ~4% savings
