Items Out of Stock
From time to time it is unavoidable that stock shortages will occur, why?
- Demand for an item is much higher than expected and our manufacturer needs time to restock our supply
- The manufacturer has an unforeseen backorder of an item due to a shortage of parts, materials, etc...
- Delivery delays can be caused by transportation strikes, natural disasters such as floods, tornadoes, snow or rain storms etc...
- The estimated in stock date of an item is subject to change at any time, but we try to maintain the most accurate information that is available to us.
Back Ordered Items
Popular or new items may sell out quickly and temporarily be put on back order while our warehouse waits to re-stock those items. Ordering an item that is currently on back order is a worry-free way to ensure that you will be first in line for the new inventory and that the item which you ordered will be sent out to you as soon as our warehouse receives it in.
