Yesterday I purchased some Accuride 26" drawer slides that, to my delight, were priced 50% off on closeout at the local Rockler store. Today, as I went about installing them, I found that they are actually 25 1/2", and that 1/2" made them just a little too short. I called and they told me there were 28" slides in stock, and that they normally don't return closeout items, but that he would go ahead. I went down and found that the 28" slides didn't have the 50% off sticker, but they gave me the closeout price on those as well.
So, not only did they let me exchange a closeout item, but they made sure I got a great deal on the new slides as well. Customer service can't get much better.
