Longtime Netflix DVD customer Moe Long was excited to receive a recent email in his inbox from the company. It included a link inviting customers to potentially receive up to 10 extra discs on Sept. 29 — when Netflix's 25-year-old delivery service goes dark.

Netflix is marking an end to the era of mailing out DVDs in red envelopes to subscribers by offering to send them these extra discs.
