Mr. Heater Portable buddies
I cannot speak for every walmart. But if you are interested in the Mr. Heater Portable buddies and for the cheap. Model MH9BX, they are being sold for $35, which is half price at crestwood, il walmart. I do not know if they priced it in their systems wrong, or what. They are advertised as $68.98 on walmart.com and more elsewhere. there were about 15 units when i grabbed mine.
