Not yet. Wholesale Pricing Now doesn’t currently support setting a specific discounted price directly — you can’t enter a fixed price (including $0) as the wholesale price.
Instead, set the wholesale price as a discount off the retail price — either a percentage off (for example, 20% off) or a fixed amount off (for example, $5 off).
We’re working on adding the ability to set discounted prices directly, but it isn’t available yet.
