thats the way to about it!
Also many many people do not know this so here is another pro shopping tip.
In the USA the labels have to clearly state a price per unit in addition to the whole price:

So when comparing different sizes or cost of items it is best to compare at unit price.
You will see in many cases that the larger size is actually more expensive per unit cost than the same item of a smaller size!
Or with stuff like cereal and other products you think a bigger box of one item is less expensive or a better deal but when you look at the price per ounce and see it is more expensive per unit/oz than another cereal you are considering.
Then you scratch your head like "how could that be when this one cost less than the other" It's because they charge you more per unit cost but then give you LESS overall product.
So you pay something like $0.40/ounce for one cereal but overall cost is $5.00. Then you look at the other ceral that is $0.30/ounce but cost $5.25.
The difference is that you are getting WAY more overall weight of product in the $5.25 box of cerial than the $5.00 box of cereal.
SO you can only know this if you look at cost per ounce and see the total weights of both products. In the end if you buy the lower cost per unit item though overall price is 25 cents more if you can afford it BUT you get like 25% more product overall!
I hope I explained that well.
Long story short, look at label cost per unit and the lower that is the better off you are provided you can afford the whole cost in the end :)
Just balance it out :)
