Don't buys/passes
Any drill bit drivers
Cheap drill bits

Pittsburgh wrenches made in china or india (once again, stick with taiwan made Pittsburgh pro)
Locking needle nose pliers. (Cheap version, haven't tried the Pittsburgh pro ones)
The cheap/free multimeter (stock up on them while you have the free gift coupons because they come in handy but break easily)
Screws and bolts

Bottom line is at Hf you get what you pay for, kinda... the cheapest stuff is the crapiest stuff you can buy. Their more expensive stuff is high quality but still a fraction of the cost of the competitors. I recommend shelling out the dough at HF unless you want really high quality tools. And I'm not talking Snap on. I'm talking SK, Proto, Greenfield, etc.. Anyways this is quite a bit of my experiences with HF. Hope this helps....
