Quick Answer
MOD Bundles = Customers visit a bundle page and build their bundle
Automatic discounts = Discounts applied when cart contains qualifying items
These are different features for different use cases.
What MOD Bundles Does
MOD Bundles creates curated bundle experiences where customers:
Visit a specific bundle product page
See the bundle interface
Select their items/variants
Add the complete bundle to cart
Receive the bundle discount
Example: "Build Your Gift Box" page where customers pick 3 candles and get 15% off.
What Automatic Discounts Do
Automatic discounts apply when cart conditions are met, regardless of how items were added:
Customer shops normally across your store
Adds items to cart individually
At checkout, discount automatically applies if cart qualifies
No special bundle page needed
Example: "Buy any leggings + any sports bra, get 10% off" — applies even if customer added items from separate product pages.
Which Do You Need?
Use MOD Bundles when:
You want a dedicated "build your bundle" experience
Customers should see items together as a set
You want to guide product selection
Bundle has a specific theme (gift box, meal kit, outfit)
You want bundle-specific imagery and messaging
Use Automatic Discounts when:
Customers should shop normally and get rewarded
Discount applies to any qualifying combination
You don't want customers to visit a special page
"Buy X and Y together anywhere" promotions
Upsell incentives ("Add a second item for 20% off")
