Yep, 32DD (E) here as well. I have also been told that by sales people a number of times as well.  They are definitely just letting you know so you don't waste your time or their time. One of the stores actually was able to special order a sports bra in my size after I found one there that I liked. Another store referred me to their website where they carried additional sizing.  I kind of got the idea that it was just good customer service and by letting me know up front that they could either a.) special order it in my size b.) redirect me to their website where they do offer more sizes or c.) can't help me at all so no point in wasting anyone's time. I appreciate them letting me know up front because that's not an easy bra size to find (in my area/location anyway) and I didn't even know that some of these stores could special order until it was offered.
