Haliburton Salvage is a great place to find home repair and remodeling items. They seem to have a selection of overstock items and pieces that came from builders who had too many of one thing ordered. You can usually find enough of the same product to complete any size task whether it's flooring, tile work, stone and granite for exterior work, wall paper, bath tubs, sinks, cabinets or miscellaneous items. They have it all and have all items marked far below retail, even though these items are brand new and never used.
Sometimes it is a hit and miss situation, keep returning and you are sure to find exactly what you are looking for.
