My best most recent purchase was new carpet for my condo. I've never had new carpet before and my old carpet was at least 25-30 years old, worn out, and badly stained.

My computer,my digital camera,adopting all of my cats,high speed internet,new dishwasher,new refrigerator,getting rid of carpet in my bathrooms and replacing it with a hard surface type of linoleum.

Some of my worst purchases have been gym memberships,treadmill and exercise equipment,shoes,some clothes, and just ending up with too much junk and/or clutter.
