Challenge One - Buying in Bulk

WOW what can I say about "buying in bulk"

I have found that there is 3 ways of buying in Bulk

#1 is buying a large quantity that is in a larger container and packaging it yourself into smaller containers
#2 buying a large quantity of something in individual containers.
#3 buying on sale and buying quantity

Example of #1
Let's take Ketchup, our family eats a lot of ketchup doesnt matter what kind it is; however we go through at least a 36 oz bottle of ketchup a week.  Our family comes by this honestly, I am a huge ketchup eater, my husband on the other hand is not.  All our girls are huge ketchup eaters, on eggs, mashed potatoes you name it. 
It was suggested that I look at the cost of buying it in cans and bottling it ourselves.  I thought sure let me see what the cost would be.  I found on the internet, I can buy bulk 6 #10 cans which is 115oz of Ketchup for $17.99 plus $4.95 shipping for a total of $22.94 making it .033 an ounce.  Our typical bottle ketchup is 36 oz so it would make our bulk ketchup $1.18 a bottle.  

Example of #2
Buying a case of Ketchup at a warehouse type setting such as Costco.  At Costco Heinz Ketchup 3/44oz $7.47 making it $2.49 a bottle.

Example of #3
Watching the ads and seeing when the ketchup goes on sale and buying more than one.  As we know for our family that we go through 6 - 32oz bottles of ketchup a month.

At anytime, I can get the same bottle ketchup for around .99cents no recycled bottles no mess and since my family is not picky on the brand of ketchup.  We are better off on the #3 sale savings.

Suggestion:  break it down and see what your family uses constantly and catch sales.
