In addition to the Percentage Discount, you can also set Sale Price and Fixed Discount to Sale Price and Fixed Discount bundles.
Note that Sale Price and Fixed Discount are available only if 1 product is included in the offer.
Both Sale Price and Fixed Discount can be seen now on the 2nd step of creating Bundle:
Sale Price
This option is perfect for stores running frequent sales or those wanting to set attractive price points for larger orders. For example, if a product normally retails for $20, a merchant can now set it to automatically drop to $15 when a customer buys three or more units.
Fixed Discount
This approach is ideal for businesses that prefer to offer straightforward savings without the need to calculate percentages.
