Cryonics Institute and Suspended Animation now have an arrangement where Suspended Animation will conduct a field cryopreservation before shipping the body to Cryonics Institute, thus decreasing tissue damage occuring in transit. They are raising their prices accordingly, but offering a discount from the new price for people who sign up by May 21 (and arrange funding within another 3 months). See https://cryonics.org/members/standby/suspended-animation-inc-standby-transport-services-option/ for details.

It is thus an especially good time to sign up cryonics if you intend to contract with Cryonics Institute plus Suspended Animation, and live in the United States. If you don't live in the US, don't intend to contract with CI, or intend to contract with CI but not also with SA, then this deadline doesn't mean anything for you, but, if you want to, you could still take this as impetus to get around to signing up.
