For an individual listing : when creating that listing go down to the section that reads Volume Pricing and follow the steps where you fill in the various percentages based on the number of items purchased.
For multiple listings ( saves time if applying volume pricing to more than one or two listings):
In Seller Hub, select Promotions from the Marketing tab - opens in new window or tab.
Select Create a Promotion, and then choose Volume Pricing.
Name your promotion, choose your pricing tiers, and select Add Inventory.
You can then select up to 500 individual items or copy and paste up to 500 item IDs or SKUs. (You can also create category rules with price filters, item condition filters, or brand filters or exclude up to 100 items, SKUs, or categories.)
When you’ve finished, select Save and review to return to the main screen.
You can edit your inventory by selecting Add or remove rules, save your promotion for later by selecting Save a draft, or choose the date range for when it will be active and then select Launch.
