Look at the big boys; how do they do their signage? Most of the big retailers have clear signage, and that's not for nothing: They've usually paid for extensive marketing research, and changed their signage accordingly to boost their sales. If your signs are very different then theirs, that might be a clue that they could be better.

I have no control over what the signs look like, I have no control over how corporate wants to price ad items. I *do* have control over sings like the yellow "price decline" signs as I make those decisions when I (temporairly or otherwise) drop my prices but, as I said, I'm stuck using those yellow signs in such situations and due to way the shelves are made (and where the signs go as a universal truth) I have no control over where they go in relation to the product.
Reading and understaning. That's all one has to do.
Large sings in bunkers -like my $3.99 steak example- I do have some control over, but things like having to make the individual price point obvious ties my hands a bit. And, as I've said, we've tried many different ways to do that kind of signage and it
always confuses people.
So. Either I can make a sing with a long sentence that says "Items in this bunker are priced $3.99 individualy and are in packages of two for a total of $7.98." Or a person can just
friggin read and
understand.
ANOTHER example:
In the ad (again, not something I have any control over as I do not write, design, or layout the ads) There's a picture of a bag of shrimp with "3.99/lb" on it,
right next to it there's a little circle written in it: "Sold in 2lb bag for $7.98." In the case where these are sold, a sign that says "2lb Bag of Shrimp: $7.98." Guess how many people want to buy that bag of shrimp for $3.99?
ANOTHER example:
In a "wrap around ad" (again something I have no control over as I do not write, design, or layout the ads) -which is a small ad that "wraps around" the larger weekly ad- there's writing/pictures on it advertising a "3 Day Sale" under which is a little "calendar" showing the date(s) of the sale, along with the days, "Thursday, Friday, Saturday." People, constantly come in the preceeding Wednesday and the following Sunday wondering why those items are not on sale. Even though the ad
clearly says that it was a 3 Day sale, what days it ran and what DATES it ran.
But, I guess we should have people at the front doors handing out the ads and personaly telling each person what days that sale actually runs. Wouldn't want them be bothered by having to, I dunno, READ or something.
What does "2/$4.00" mean? 2 divided by four bucks? That's really confusing. A better way might be "2 (name of item) for $4.00", leaving no room for error.
Maybe this is a national/regional thing. But "2/4.00" means "2 for $4.00" pretty universally here. (The signs might actually say "for" as well rather than using the slash.)
No. What you're saying is all true, however, simply putting "lb" is not the most clear way of putting it. "per lb" would be much clearer, for example.
Again, this might be a regional/national/language thing. Where having a small "lb" at the end of the price pretty universally here means "per lb."
