Change prices no longer drops a product to nothing by accident

A bulk price change that would take a product under one cent leaves that product as it was and tells you which ones.

Change prices on a selection of products skips any product whose new price or sale price would land under one cent: a percentage, an amount, a markup on a card that cost nothing, or 100% off. It keeps its price and its sale price, and the notification names it.
Set to an amount still does exactly what you type, zero included.
The window now says how many products you selected.
