We have ordered the P--I--S pump for the lactation center and have sold them fairly rapidly. So far, mothers seem pleased with it. I am not recommending it for moms with difficulties yet as I do not have a track record. I am requesting that the mothers who purchase it from us let us know how they like it. Ruth also asked about returns. I suppose we will treat them like other products. We do not make a practice of taking returns; however, if a mother is not pleased, we will take something back to keep a happy customer. If there are many such returns, we simply do not continue stocking the product. Our pricing follows the mark-up formula for outpatient lactation supplies which is a lower formula than that used for inpatient acute care supplies.
