The shop should move into your assigned shops. You will go there click on it and it will have instructions. Every shop is different so you will need to know how that shop is set up. Contact the scheduler or MSP if you are unable to locate the GUIDELINES for the shop.
You must be careful taking anything paper into a shop. You should never take anything in print from the MSP into the shop location. Now if you had written things down or created a computer generated list that is different. But anything identifying the MSP or the client would be an ethical violation of most ICAs.
In the matter of price audits, if a store manager observes you taking down prices that is against most stores policy and they would be within their rights to have you removed from the premises, Writing leaves YOU vulnerable to being identified as a shopper and price audits completed for the competition of a store is a gray area because we are ICs. But if say Wal Mart sent an ACTUAL employee into Wal-Mart to collect pricing information that is illegal.
All I am trying to say is be careful. Protect yourself, the MSP and the client. In order to complete my shops accurately and safely I use a digital audio recorder connected to my blutooth. Most people assume I am on a phone call. I can record notes to myself and refer back to them later. There are no written notes that any employee can see and they can only know what they overheard and I am careful not to speak when people are near.
I also use a LiveScribe pen when I can't speak. I write my notes on paper and the 'pen' transfers what I wrote onto my device. I can then flip the written words into text and insert it into a report or message or whatever I need. I can instantly add shops to my google calendar. At the same time my phone can record audio and I can pull all of it up later when I am completing my reports.
