Working here in Res, I did look for the whole week, since was not sure of which day you are looking at. I see inventory there, but......We are not seeing U(nwa) or Z/G(delta) upgrade inventory....I am not saying its not available..it just not showing on our end....as upgrade inventory is showing blanks....need to see if can get an agent to "long sale" and "NN"(NeedNeed) it into the reservation to see if can get that processed for you.
Good Luck,
