Service - Sell Offer Price
Overview
Standard pricing config that can be shared by many sellOffers. Can create other pricing services in the future, each SellOffer Handler service chooses which pricing service it uses (or many if it wants).
A user can point their sellOffer standard to any sellOfferPrice, even ones created by other users, but only the user who created the sellOfferPrice can change it.
