I imagine the stores are not in the business of carrying expensive inventory that goes obsolete quickly or is at the whim of the public. Same with the online operation actually.
As was mentioned there are all sorts of unlocked phones available.
Also most Speakout users probably are content with what they provide as I know of a few that still want the basic flip phone when given a choice at the same price.
I will say the previous BLU were a disaster for my wife and her sister. Both have sent theirs in for replacement and one of ours was "just" out of warranty, so three problems with 2 phone purchases and never had that before with any other brand.
