Sigh. So, here's the deal with Blink/Equinox Memberships. The Gray is the one that gives you privileges at just one location...the other plans give you access at other locations, say near your office and home. Here's what's in plain English on the website:
1.) If you cancel, by signing up, you already agreed to give them 45 days notice...so they can charge you two months membership if you cancel after the 15th of the month, since they hit you up on the first.
2.) Blink charges an Annual Overhead fee, that goes to the operating budget and maintenance. Depending on when you cancel, (say after your anniversary) they can legally hit you for that on the way out.
Read your contracts before you sign, people!
