I know I am dreaming but hey...
I would start calling around - I know that as of about a month ago these colors were still out there !! I purchased an Anthra GGH Hobo from BalNY in February, and I know NM in Short Hills, NJ had some Plomb bags left. I'm not sure if either store would have an RH Work, but it's worth a try!
so tempted by this NM sale
^^ You should go for it if they have any of the 2 you are looking for! Though there was a Plomb Work couple days ago that didn't sell.
