Reno depot has a deal on their "Bazz" branded LED lights. Buy a $10 light bulb get a $10 gift card. We were buying a bunch of stuff for a renovation (bathtub, etc) so bought a bunch of LEDs first and then used the gift cards to pay for stuff we're using anyway. I haven't tried the lightbulbs yet (busy with renovation stuff) but the price was right.

It's in their flyer, and the deal is good until Nov 2nd. I bought a bunch of A19 and GU10s. I've already replaced my kitchen pot lights with LEDs, and they've lasted so much better its unbelievable.
(I think the reno-depot gift cards are also good at Rona stores, since its the same company, but haven't actually tried that)
