Shelf Tag

Shelf Tag

n. An ITEM'S PRICE TAG, affixed to the shelf supporting it, at the leftmost edge of the ITEM'S HOLE. See also DANGLER.

NOTE: There are many different types of Shelf Tags, including the REGULAR PRICE tag, SALE PRICE tag, DISCONTINUED tag, and so on.

If the Shelf Tag you need to look at is missing, take the ITEM in question to PRICE CONTROL to SCAN its UPC with a GUN in order to get the STORE CODE, and to perhaps also learn whether or not the ITEM is currently ON SALE (although one of the STORE'S in-AISLE PRICE CHECK SCANNERS may be able to tell you that). You may or may not be instructed to leave the ITEM you brought, in order for PRICE CONTROL to make a replacement Shelf Tag.

Moving Shelf Tags is a no-no. You only do it if you've previously gotten instructions and/or permission to CUT IN a new PRODUCT or to expand one HOLE at the expense of another.

DETAILS: Shelf Tag ANATOMY. OK. Fair warning: this is the deep end of the pool. At one time I wondered what are all of the things that make up a Shelf Tag, or, what would the definition of a Shelf Tag look like? So, I tried to write one. And that's what you see below: the results of my research at one particular point. (Doubtless Shelf Tags will continue to change over time, so please just take this as a demonstration of principle.)

Now, if the definition happens to look a little strange, that's because it's written in computer-ese. More specifically, I used what one might call a loosely written modified Extended Backus-Naur (BNF) form with POSIX and GREP extensions.

Say, “Eh?” Well, the overall idea is simply that you have to define things as you go, taking absolutely nothing for granted. For instance, as you'll see below, even a single “LETTER” must be defined, here as one thing selected from the list “[ ]” of capitals and lower-case A through Z. Likewise, “*” means “zero or more;” “+” means “one or more;” “|” means “or,” and so on. In just a few moments, you can probably get the hang of it.
