Well that's the embarrassing part, the invoice seems to have completely disappeared into thin air. I'm usually good with receipt-keeping, and I've found every Electrical Direct invoice *save* the one for the damned timer. Even more extraordinary, I don't even have the order confirmation email - I have four 'dispatch' emails from ED, but only three 'order received's, and the fourth would have been the timer order. o_O
It was only $40, and the packaging says 'must be installed by registered electrician' anyway (does an EAS cert count?).
