Oh, that's interesting, Mo. I ordered some earlier this week and they have shipped. I ordered petite though. (I actually ordered a regular last week and it was very long. I could have just shorted the straps but figured since I could just buy it in petite, that would be easier.). I liked it a lot by the way- soft and not clingy or riding up. I sized up but that's mostly because I prefer a looser fit for my camis.
Anyway, yes the sale price holds for back ordered items. They don't charge your card until it ships. Sometimes you get lucky and get a return. (not your size, unfortunately, but I sent a L olive back this morning.)
