A professional floor person measure and install my wood floors. When he was done with the job we had 13 boxes of flooring left over. I tried to return or even get a credit from Lumber Liquidators. They told me it was past the 30 day return policy. I can see maybe having 2 or 3 boxes left over but 13. It was so busy that day when I placed the order that I think the sales person at Lumber Liquidators calculated wrong.
