I didn't know that the adhesive ones aren't used everywhere now.
I have nothing but bad things to say about them, so hopefully corporate does read this and take note before expanding them everywhere.
They are a royal pain to put out—the backing isn't always cut right so that there is a lip to separate it from the adhesive on the flag.
The backing ends up statically charged and clings to everything—carts, product, shelves, the floor, people—and we're talking thousands of little 1"x3" strips per week.
About 25% of the signs fall off by Monday, and probably half by the end of a week—I probably spend an hour a week putting signs back on the shelf. Multi-week (TPC) flags have almost no hope of making it to their end date.
Ironically, those that don't fall off somehow chemically bond to the sign strip, and leave what looks like an adhesive blank covering the shelf label perfectly. If you don't notice right away, flow team will push any product into that space thinking it is discontinued.
I can't think of a single upside to them over the old signs I've used in the past. In theory they seem easier, but in reality they definitely aren't.
