Hi Kate

Agree with Catherine. You are on track with the initial assumption that many retailers are looking for a 50% margin (keystone pricing). Great to do research and work back as it can be very industry/retailer dependant. You might find that your market can take a higher RRP for your product. Giving you more margin and in turn more profit/flexibility (such as offering volume or booking discounts, sales, etc). Always easier to reduce price than increase price.

I hope that helps.

Cheers
