If my supplies cost me .50 I sell to boutiques for $1.50 then they usually mark them to $3.00. My bows that cost me $1.00 I sell for $3.00 and they mark to $6.00.
If I was selling at a show my bows would be $3.00 and $6.00. So technically it is a 50% with mine, but I've already got my mark up before their so called 50%. Don't know if that made any sense or not.
