My cheap domestic thrills:
Seeing the inside of the fridge looking all spick and span after I have cleaned it, I can't stop opening the door to have a look for at least 24 hours.
Having a good clear out and then having the ability of opening drawers without having bits of paper sticking out and having to force them back in.
A new toilet roll on the holder instead of an empty one and the new one residing on the floor.
Polishing your bathroom mirror and seeing yourself in your full glory instead of a blurred vision surrounded by splatters of toothpaste.
Watering your dead plants with TLC and slowly watching them spring back to life.
Walking into your kitchen in the morning and seeing clean surfaces instead of yesterdays pots and pans.
oooh I could go on....
