Like anyplace, once it's been open for a bit, they'll have a 'open-box & returns' table. Stuff there is usually heavily-discounted. I got the larger flux-core welder from one of those tables, it looked like it had been powered-up, used very little and returned. I got it for a bit over $40. A couple of around the house jobs, and I got that out of it. It's the model that there are a bunch of youtube videos about hacking it for better results.
I was coerced into buying the Inside Track Club membership, but didn't bother renewing my membership, I didn't think I was buying enough of the sale items they offer, to make it worth my while. At the time, I was able to make one purchase that paid for most of the membership cost, so I got it.
I think HFT offers a good value for the $. Not everything they sell is gonna find its way into my home, but there are enough things they sell that it's worthwhile to shop there.
