How do I determine bulk pricing for my product?

Hi,

I just reced a call from a resort spa in my area and they want to sell MY organic skincare line in their resort style spa!!!!! They asked about bulk pricing and to be honest I’ve never sold in bulk before. I just sell a few items online here and there and also at health expos. I don’t even know how to begin pricing my products on a bulk level. I want to take the opportunity, but I don’t want to loose any money. Can anyone help me?

Please help.

I didn’t find the right solution from the Internet.
