Update: Just realized the $10 only works in-store. Apologies. Ted's should match their online price in-store though.
I've been trying to find a cheap price for the revised, STM version of the 'plastic fantastic' or 'nifty fifty' as it's called but nothing has come close this mark since I've been checking. This is part of their Boxing Day sale which started early online.
$140 is pretty good for this since the cheapest previously has been $131 on here via Kogan on eBay. Kogan are selling them for $149 at the moment plus shipping (no local pickup option). Cheapest online is $129 plus shipping. But $140 for local store and local stock is pretty good for this fantastic lens.
You need to sign up to get the $10 voucher for this.
The Canon EF-S 24mm F2.8 STM is $179.95 after the $10 too which is not bad. No discount on the 40mm.
My pick would be eos m3 kit with canon cashback around $400 until modnight.
