The problem with their schedulers is that they work form home, and the editors are in Europe so they think that a $10 fee for a retail store in an area where $7 is the meter parking is a great fee. Only when the shops stay and more senior schedulers are in charge the fees reach reasonable and better range. Another point you need to think about, if you are in a major metropolitan area with luxury shops, you might want to do a few of them to prove with ISC that you are a reliable shopper so you can negotiate higher fees and get good reimbursement shops. I have done clothes and accessories with reimbursement from $70 to $250 for clients that only have 5-10 retail stores in the entire USA so they do not show often. They also have mid-level shops that in Europe they consider them luxury brand.
They have clearly developed a long term relationship with the majority of the European headquartered luxury branches and have taken over most of the clients that I can not remember now the name but they were done by an MS, still is in existence, that is located in NY, proprietary website and did the high high end clothing, watches like the ones that they fry the pins, the Sex in the City favorite dept store, etc and one of their main schedulers (male) was in Miami.
