Sony MDR-ZX110NC noise-cancelling headphones – $47 at DELL with $25 egift promo & $25 in Advantage Rewards

I was only looking for this to roll an expiring Dell egift card. $25 back in egift card for certain audio purchases , in addition to $25 in Dell Advantage Rewards for Sony purchases .
$47 is not that great in itself ($32 now at Amazon) but they won’t pricematch with the promo codes.
