Be careful.
Most Best Buy stores will sell u Verizon full price iPhone. But the two I went to in orlando wanted $50 over msrp.
I told them msrp for 64gb plus was $850 and they insisted on selling it for $900.
U may get the right Best Buy to "price match".
But some Best Buy won't budge especially when 6S plus was in high demand.
Maybe now that demand has caught up to supply u can get them to price match.
