I mentioned this in a forum I just posted, but in case you didn't read it, Davids Bridal is discontinuing a lot of styles of their bridesmaids dresses.
If you check their website a lot of the dresses were on sale this weekend (through the 30th I think).
I only found out mine were being discontinued because one of my girls went in to buy it and they told her then. My girls had to all scramble and pray they had their sizes left but they all thankfully got them. This was a newer style dress, too. Only a year or two old.
If your bridesmaids have been ordering from there or plan to order from there make sure you grab the dress you want before its gone!
