Looks like a decent deal $4188 after Cashback + $200 Gift Card. Looks like you can get an additional 2% off with Top Cashback too. With the 2% off topcashback at $81.60 + giftcard (if you'd consider that) and the Sony cashback it'll be $3906.40 which is an awesome price.
Please OzB gods, please post a better deal if you believe there is one out there.
It would be $81.60 cashback. Calcs are done pre-GST. Still, $4488, minus $300, minus $200 (if you could the gift card as cash), minus $81.60 = $3906.40
