Why aren't all products in a sale highlighted in green?

Question

Why aren't all products in a sale highlighted in green to indicate the sale price is active?

Answer

If a product is in more than one active sale, GlobalTill will select the lowest sale price from all active sales. If your sale is in Status: Active, but there are products that are not highlighted in green, it is likely that the unhighlighted products are active in another sale with a lower sale price.
