Go to their website and sign up for their flyers if you haven't already. They often print a 10-15% off coupon beside the mailing label to get you in the store. You will also need an argon tank and regulater to use it, or the tank can be rented for a few bucks a month. IIRC, my local welding supply quoted around $110 filled for buying one of their tanks, 80 cubic foot size. HF has an argon reg for around $30 or $40?
