I concur with Steph D's review. They suffer from a dire lack of awareness in regards to managing their inventory. I am a medical sales professional as well and I've had to make last minute accommodations for offices. For them not to sell more than 12 at a time to any given person at any given time shows an amateur level of planning followed by misguided customer service. There are too many options in the market who are prepared to accommodate the needs of their customers.
