Here is a tip concerning the big bottles of cooking oil. Rinse out a smaller container with some sort of pouring/squirting Spout and fill it with some of the cooking oil from the larger bottle. This way it is much easier to get just a tablespoon or whatever Without spilling and wasting extra. I use an old lemonade concentrate container and it works great!
You can also buy empty pump spray bottles at some beauty supply stores that have never had chemicals in them. You can wash with a mild soap and rinse well and dry out. Add your oil or olive oil, etc. This can replace the non-stick spray that costs so much.
Re Syd's recommendation to use contact lens solution bottles for cooking oil - there are other additives to saline and in some cases mercury has been added in the form of thimerosol!
As an additional comment - I buy the huge containers of oil (restaurant sized from Costco) and then pour into a 10 cup wide mouth measuring cup which I fill a moderate sized container and a small oil container. I haven't bought more oil in over a year and I still have tons left!!
This tip can be adapted to any household liquids to make savings. I like pump action bottles as you can use a measured amount. A bottle of washing up liquid lasts for ages if you transfer it to one of these. Shampoo, conditioner, bleach, sauces, etc., can also be measured out with these bottles - especially helpful for children to prevent accidental overuse.
Rinse out the old saline bottles used for rinsing contact lenses and fill with oil.
Saline is salt water!
