“I had a gig coming up and we were going to play Sammartini trio sonatas. They had them online in a Shott edition. I could not find if the sheet music had a realized BC or not... so I called. No way to get anyone there to actually look at the music and answer a question. I added a note on my order to please look.. no response. I got the music and the BC was realized so I was happy and the gig went well.
Sammartini is listed twice on the web site (I mean the same brother twice...) so it was confusing to find the music.
Two suggestions: Put a preview page on the web site for each piece. Run a dup check on your catalog DB.
