HOW DO I CREATE VOLUME-BASED PRICING FOR A GROUP OF PRODUCTS?
A seller may have several similar products
for which they would like to create volume-based pricing and/or tiered
pricing. For example, a seller may sell ketchup. If a buyer purchases $500 of
products, the seller would like to give the buyer 10% off.
To go one step further and create tiered, volume-based pricing,
you’ll want to create multiple promotions for the collection of ketchups that stand alone from eachother For example, you could create one product that takes 10% off the price when someone spends $500 and a second
promotion that takes 15% off the price when someone spends $700.
These stacked promotions effectively create pricing tiers for your
collection of ketchup products.  Here's an example:1st Product Listing:  3 x 16oz Bottles of Ketchup2nd Product Listing:  12 x 16oz bottles of Ketchup = $363rd Product Listing:  48 x 16oz bottles of Ketchup = $129.60 (10% OFF)4th Product Listing:  96 x 16oz bottles of Ketchup = $244.80 (15% OFF)So you create 4 different Tiers of Pricing by creating 4 different Product Listings.
