99sikolaiey12 As phone-company wrote, if Amazon is the seller (not just the shipper), it's likely ok. But be aware that buying an expensive popular item on Amazon from a third-party seller has risks. If Amazon receives stock of some item from Seller A and Seller B, and you purchase from Seller B but you live closer to Seller A, Amazon may ship you Seller A's item instead. Sometimes the buyer ends up with the wrong item, in which case Seller B may get a bad review even when a mistake was made by Amazon or by Seller A, and the situation can take a while to untangle. This might happen more if the differences between the two items are very subtle -- such as, perhaps, OEM-unlock status.

If you want exactly the right thing, the safest place to order from is Google. Ordering from a reputable chain is probably second-best, and probably good, as long as the product is sold by the chain. Third-party sellers, on any platform, pose added risk.
