If you want to talk about lucking out with things, I can tell you about this past week! I was looking to buy a portable air conditioning system as well as air filters for my regular central heating and air conditioning system. And would you believe that the local heat and a/c dealership happened to have both on sale! Both at the same time. You had the portable air conditioning system on sale for 40 percent off and the air filters for my central heating and cooling unit on sale for 50 percent off the regular price. This was like the major week of HVAC sales or something! I am not needing a brand new and up to date central heating and air conditioning system, so I did not bother to look to see if they had them on sale as well. But I would bet anything that they probably did. It is not often that you find so many things on sale at the same store at the same week. Especially when it comes to heating and air conditioning related things. The HVAC dealership that I go to is really great. They never stop amazing me with the HVAC products that they sell and the sales that they have. I can tell you that I am always on the look out every month to see what they have on sale. Because you never know what is going to pop up and what could be useful. Especially air filters for the central heat and a/c unit. They seem to have those on sale a lot!
