Most of the stuff I have bought there are pretty good deals. Mostly hand tools, tarps, rope, boxes of cheap fasteners, grommet tools, etc.
For reasons that escape me, people will try and compare grade 5 bolts to the cheap boxes of nuts and bolts HF sells and then complain about the quality. Of course they are a lesser quality than an expensive fastener but the vast majority of the time the cheap one works just fine.
Same with their tools. Most of their hand tools are just fine for everyday use. They come with a lifetime warranty in most cases anyway. To be candid, I have had more craftsman tool problems than HF.
The electric corded and battery powered tools have not been up to snuff though until recently. Their recent battery tool lines are every bit as good as upper grade consumer lines like ryobi.
Want a real bargain? Look into their tool carts.
