If you pick your battles wisely, you can walk away with some amazing deals from this site. I've been disappointed my fair share of times too, but if you stick at it and play the a professional, you will win.
I've won multiple lamps, clothing, shoulder bags, kitchenware items, and pieces of jewellery, and aside from the time invested, I've put in literally $1. (Opened my account with a $50 gift card won for $0.19 on Deal Dash.) Can't beat that price.
