I believe that the sale prices for HF are cyclical. Like everything there are good and bad deals at HF. I for one never buy anything that isn't on sale and don't have a 20% off coupon. There are certain things I like from them and a lot of junk that I missed the 30 day window to return. So...
1) Air compressor
2) Robo-grip pliers that I always think will do the job and start to slip at around 2 in-lbs of torque no matter how hard you squeeze.
3) For my son to be old enough to hang out and help.
