I don't want to detract from your good fortune, however....
I also buy some stuff from HF. Be careful what items you choose. I've seen problems with a number of their electrical tools (planers, drills, angle grinders). These were not items I bought, they were bought by co-workers. The worst incident I know of was a co-worker who was using one of their long, screwdriver-like pry bars on his truck. Suddenly the steel shattered into tens of pieces. He commented he was lucky that none of the bits hit him because the debris dented the inside of his truck's wheel well and he was finding pieces of the shaft in his shop for days after.
That said, they do have some deals. Just exercise caution when making your decisions.
