So I was over at my local Lowes today and noticed they had a piece of double walled, stainless lined stove pipe on clearance for like $4 and change. I took a look online and noticed that there are quite a number of random pieces that are clearanced at stores nearby. You'll have to change it to your local store and click the button near the "store pickup" to find inventory levels. It seems to be items that are in limited stock at that particular store. I was able to pick up a few pieces at 85% off that will definitely be put to use. Good luck to all....curious to find out if this is just a local thing, or if others have luck also.
