A lot of Samsung products were heavily discounted during this Black Friday, and the discounts are still running. Currently, 32GB variant of the Galaxy S6 and 128GB variant of the Galaxy S6 edge are being sold for as low as $399 and $599 in the US. These devices are compatible with Verizon's network, and are available through eBay.
The current non-discount price of the Galaxy S6 (32GB) is being sold for $580 on Verizon's website, while the price tag of the Galaxy S6 edge (128GB) is $899. This deal also includes free shipping in the US, but only a “limited quantity” of units are available right now, so you better hurry if you got your eyes on them.
