It would speed up the process of accepting buy orders by adjusting multiple buy orders containing similar cards. If I update a card's buy price on the "Inventory > Products" page and there's multiple requests to sell the card, I would like the system to update every buy order with that card that's still "Awaiting Approval".
On a similar note, you could also show the "Current Buy Price" under the "Product data" of an "Awaiting Approval" stage of a buy order. It wouldn't immediately update the buy price, but I wouldn't have to open another page to see if the buy price has changed. It would also help if there was a time-stamp on when it was last changed.
you'd need to notify EVERY customer of buy orders altered this way and get confirmation before completing the buy order. otherwise it might be considered fraud/ bait n switch.
I don't think customers will be happy if we quote a price, then pay another (lower) price. Not everybody reads the approval notification. Please don't make it automatic, it sounds like more work to change the new prices to the original quote.
