Availability is not guaranteed, but we will try hard to get you what you want. There may be items which will not qualify for a discount due to low inventory levels. If an item does not have inventory available for a discount, the full price will still be listed and you can add it to your cart. In these cases, you must process the items in your cart in two separate transactions — one for Pro items and one for regularly priced items. We cannot allow back orders on unavailable items.
