For a single mother of three kids buying clothes is a major expense but ebay has been a life saver.  You cn find nice clothes for both boys and girls in all different sizes.  Just be careful to watch the shipping.  Sellers have to pay a percentage for the merchandise they sell but not on the shipping so they sell the merchndise cheap then charge you an outrageous amount on shipping way beyond what it really costs.  Check the feedback but remember when you do that there just are some people you can never make happy and no matter how good the transaction was they will give a negative.
