I think that is a reasonable price for pure cashmere scraf.

I just got a couple scarf for my in-laws-to-be from Macys. It is soft and really warm for them.For your purpose, it is enough to be a gift. The most important thing is your sincerity, right? Don't go too crazy about the brand name or designer.For me, A pure cashmere scarf is always better than a wool one,no matter if that is brand name.
