I don't think there is such a thing of $50 off from the local set.
From Sunday experience at tpy, the shortage of local set is driving up the demand and that's why most of the shops are retailing at >$340 from where I asked. Most of the export sets are going near $290 or somewhat that range.
With only one shop selling $275 but their online price is $258. When I asked if they can sell me at the online price, they said they can't. But they can sell me at their online bundle price of $258+30 (which includes a glass protector and silicon casing )
