I love Apple, Google, Samsung and pretty much every company
.. I buy them all. But I can never get the kind of deals I generally get with Samsung from Apple or Google.
For my S10+ even though the price is $999 + tax, the trade in deals for Note 8 or G7 was crazy. I saved $210 dollars instantly since I picked up Note 8 from eBay for $340 and I know many people who picked phones for trade in at even lesser price. And the Galaxy buds adds another $130 worth of discount since I was going to buy the buds anyway. So there is a big discount from the total price which makes it a screaming deal.
The trade in deals for Apple or Google or in general most companies are not great and generally you end on the losing side compared to the launch trade in deals Samsung offers along with pre order gifts.
I have not looked into the Xr trade in prices in detail but I'm pretty sure they never offered or offering $550 for Note 8 or G7 or iPhone 7 plus (which is the Note 8 equivalent for Apple). Sure they offer trade in, but instead of those rip off trade in prices better sell the device yourself. The only time I generally consider trade in is during Samsung phone launches
Edit: Also I'm talking about just unlocked models, full price. Sure carriers offer all kinds of deals for most phones with their usual bill credits, adding line or whatever, but just taking straight unlocked model no one offers deals like Samsung IMO.
