Grab Galaxy S10 and Note 10 at bargain prices ($380 off) - Costco and T-Mobile - Android

It's the Friday that is Black and the deals are pouring in! Costco has Samsung's latest and greatest shiny, powerful phones at killer prices! These promos are valid with a verified activation on T-Mobile's network. Take note: you don't need to sign a new T-Mo contract if you are already an existing customer. But you do need to be a Costco Warehouse member, so that's where the strings are attached.
