Mid Century Cabinet $15 - For $15 this has a lot of potential.
Persian Rug $650 - Although I don't think this is a steal, its a gorgeous rug and would sell for over $1000.
Set of 6 Parsons Chairs $100 - I don't love these as is but you can buy Parsons Chair covers at a lot of stores, the price is good for the base chair.
Pottery Barn Simone Curtains (4 Panels 96") $100 - This is a great price for all four 96" panels.
