Can you cancel that order?

Rebuilding appliance timers is a cottage industry. Normally, in every major city there will be several people that rebuild appliance timers in their basements or garages for a fraction of the cost of a new timer. Just phone around to the local appliance parts stores, and the people working there will generally know who, if anyone, rebuilds appliance timers locally.

Alternatively, if there are no local places that do that kind of work, you can send your old timer in to Turner's Timers and have a rebuilt timer sent to you. I'd at least get a price for a rebuilt timer from them before you commit to buying a new timer.
