Discounting products with not enough profit?

[YuccaGirl]

Hi, if I have 5 products for sale at the same price, but some of them have less profit in them, what happens if say 25% off was applied to the whole collection, and after deducting that im negative profits on some products? 

Am I going to owe money on the transaction? Or Is there a way to apply discounts to only products with enough profit in them? 

Thank you

Why would you owe money? You might lose money, but you shouldn't owe money.

You shouldn't be offering any across the board discounts for a higher percentage than your profit margin. Only offer those large percentage discounts on higher margin items.
