[Walmart] Possible Koodo iPhone SE deal at Wal-Mart Dec 6
Assuming you can get switched to seasonal hold and can self-refer the cost is:
$360 phone + $45 for seasonal hold + tax = $457.65 - $250 gift card - $50 self referral = $157.65
Wasn't following the black friday deals so maybe this isn't that hot, but considering they're selling for $150 used getting brand new for that price seems decent.
EDIT: Went back for my adjustment today, and while I was there I double checked and as of 1:30PM it's still $200 GC on Koodo Tab M, and the bonus $50 GC is on for Wed and Thu. From what he said the $50 GC is guaranteed to be on offer for the next two days, but the $200 "base" GC could change either way at any time.
