discouraged by constant price increases

Has anyone found that there are specific PS who raise their fees and cost for procedures every month or so by 5-15k? I scheduled a consult with an NYC PS for end of June at end of April, when I contacted the office to reconfirm the consult this week, I was told the prices went up again 10k (or 20k total since I originally wrote them in March)

Is this normal for most PS or what would be considered an average rage of cost over say a 6 month period?
