Yes, you are right. I buy everrtinng at Sam's Club and the rest when on sale, I hardly ever pay regular price for anything unless I can't find it on sale. When it is I stock up on it and freeze it or store it, including paper goods.
I think I save 40% on goods this way. Sad thing is, some people I talk to are just too lazy to do this, their loss. Same people that have to have a new car every year to keep up with the Jonses.
When they get old they will wonder where their hard earned money went. JMHO. Off the soap opera, sorry for ranting.
