Mine are related to home renovations.
We decided it's in the budget to put up insulation and siding on our house this summer.
-instead of doing it totally DIY we're hiring a friend of a friend, jack of all trades guy (he's already done our roof and we love him). DH and I will work with him (cheap labour) but love that it will be done right, no second guessing.
-he wrote up a material list so we'll be shopping around. Found some great deals for Reno Depot (part of Rona) including buy 12 of same item and get the 13th free, they say they beat others prices by 10% (and will give a discount if you find it lower elsewhere) AND my mom has a bunch of coupons (spend $250 and get $25 in gift cards etc). I found all this by looking at their website and plan to print it up for when we go to the store.
-we might do our floors later this fall and supposedly we can borrow a floor sander from BIL's uncle. He bought one when he refinished all the floors in his big apartment block. You never know who owns what!
-also, adding extra insulation in the attic and vents in the peak of the roof on each side has made a HUGE difference this summer. We have a 1.5 story home and the upstairs was SO HOT last summer. (And cold in winter).
For people who have high heating/cooling bills I highly encourage you to INSULATE! It will be your best friend. Also, there are so many grants around. Check your provincial/state/federal government websites.
We have electricity through Hydro Quebec and you can do a home diagnostic by filling out a questionnaire. They use the info from your file and say roughly how much you spend on heating, hot water, lights, laundry etc. I loved it!
