Restock case quantity (gatorade, snickers etc.)
Alternate bar-codes. Occasionally a manufacturer will issue a new barcode for a product. It would be great to be able to have multiple barcode lookups.
Set discounts for a transaction instead of by item. Example 'intro pack' Customer buys shoes harness chalk bag etc they get 10% off all items. Right now you have to select each item and enter the discount on it line by line. Setting a discount for the whole ticket would be great.
