Before we dive in, some buying advice. First, you can get discounts right now by shopping for refurbished items from Apple proper. Currently, for example, the refurbished Apple Watch Series 3 38mm is $239, a savings of $40. And you can save $80 on the refurbished iPad Pro 9.7 (32GB). Apple's certified refurbs are usually indistinguishable from new, and have the same warranty as their new counterparts.

T-Mobile is offering free Apple Watch Series 4 when you join them with two eligible lines. Score!
