This is my dining room looking into the kitchen. The hutch came from the Salvation Army Thrift Store, the chairs from the Goodwill Store, the table under the fan was from my Mom's estate, the table on the back wall (behind the fan) came from Unique Thrift store as did the cat tower on the far left. The table under the pass-through was bought used along with the sofa and loveseat from a guy moving out of town.
I buy all my clothes at thrift stores except for socks and underwear. Just recently, my computer monitor died and I bought a used one from a store that recycles old computers.
This is not so much because I am noble or thrifty but because I don't have any "disposable income". Of course, that may well be due to the proven fact that your expenses will always increase to equal your income.
It sure would be fun to test that theory on a higher income, however!
