A friend of mine who is very bad with money and his girlfriend bought some sort of water filtration system from a door to door salesman. He has to pay something like $300/month for this filtration system. He was all stoked because it came with a free set of pots and pans.
Fast forward a year and his girlfriend has broken up with him, moved out of the house, and he’s had to sell his home because he can’t afford to live there. The water filtration system is now sitting in a storage unit where he still pays $300/month for it because he’s on a 2 or 3 year contract (sorry the details are fuzzy).
We have great water quality in my area.
