What a priority number actually protects
A priority number is the order in which Paynow-verified booking fees landed for that product. One product, one list. Colour, storage and shoe size are preferences stored on your booking. They do not let a later customer step in front.
Quantity
If you book three units, allocation still walks the list in priority order. You can receive all three, or fewer, depending on how many units the supplier actually committed. You cannot be skipped because someone behind you booked more.
What it does not do
It does not freeze a price that a supplier has not agreed. It does not survive as a public demand number if the payment never verifies. Demonstration and training records, if staff create any, are excluded from the counters you see on the product page.
