Just today, my husband and I had no plans of buying any home equipment.  But we were encouraged by this sales person who keep talking about an air fan and how it is cooler than an electric fan but much cheaper, in terms of consumption of electricity.  So in the long run it would be cheaper.  That seller employed by that particular company to do sales talk is really good and obviously was oriented regarding Sales Promotion by his employers.  I noticed it was not only me who bought home air coolers (with ioners which is good for the health) but there were many others.
