Regarding pricing, folks need to keep in mind Samsung, like many Asian based companies, has a tradition of offering freebies as well as generous inclusions (usually adapters for every imaginable need) to sweeten the deal. Even the bargain priced Chinese flagships come with stuff like free preinstalled screen protectors. It's not an undercutting methodology but seems to be part of Asian mercantile customs.
I remember being so confused visiting friends and family in Asia and even now ordering stuff from Asian vendors on Amazon and EBay and having armful of free NICE goodies thrust at me. The merchants, seeing my confusion, explained it was a custom to encourage a positive feeling toward their business.
I was surprised to learn last year when I gave Samsung a try that they've got quite an ecosystem of their own, very marketing oriented where you end up with a lot of deals and free stuff. They cut a lot of deals with carriers, with Amazon and other merchants. Using Samsung pay can earn rewards that are actually practical and useful like credits toward purchases with vendors I'd actually patronize.
Lol, with Samsung my husband and I practically got paid to get our phones. We got my S7 Edge for free. My unlocked S7 was purchased at discount for $500 and came with a free Gear VR headset that I badly wanted (and really enjoy) plus their version of AirPods (okay for free but not worth the price they ask) plus free Gear S2 4G watches for him and for me, free 256GB top quality SD cards for him and for me. And because of the Note 7 recall we got to keep stuff that was packaged in with our Note7s so we had extra chargers, adapters and good quality earbuds.
The phones we ended up with after recalls and loaners were returned have been excellent. Where my iPhones have my Samsungs beat is in iMessage and the overall benefits of iOS over Android. Some would argue that Samsung and Android is better. I'm not here to get into that.
I'm not here trying to sell anyone on Samsung, because there are loads of legitimate reasons to NOT go with them, I just wanted to explain what's built into their pricing structure. It's more than meets the eye.
