Roughly 30-50% off to stay (older reports)
Multiple first-hand reports describe GameFly's online cancel flow interposing extra screens, and after you pick a cancellation reason, showing a discount promotion to stay — 30% off in a 2008 account, and about half off the regular monthly price (~$11 at the time) in a 2012 account.
- Where it appears
- Screen shown after selecting a cancellation reason in the online cancel flow (Account > Cancel My Membership)
- Fine print
- Documented datapoints are from 2006-2012; no recent public confirmation found, so treat as possible but not promised. Reportedly not shown to every account, and canceling repeatedly to farm the discount was already flagged as unreliable in the 2008 report.
