Buy Small / Save Big

Instead of buying in bulk, I use coupons on the smallest package available which lets me purchase the the item for the greatest discount.

Another option is to wait for the larger package to go on sale and use a 
coupon to get it for even less.

In our area a store doubles coupons to equal $1 or less, which makes some 
name brands cost only a few cents when they are on sale and I use the coupon.

One important thing about stocking up: Don't forget to rotate your products as we purchased automatic dish washing liquid and after a year it separated and would not go back together.
