Oops, forgot to include that. Yes, that's the reason. The dressings and the mayo don't have particularly short shelf-lives, but they're the last things people expect to expire usually, and they come up in our SDA at least once a month. Hostess stuff and the AF/SB chips especially have short shelf lives.
If memory serves, salad dressing has a shelf life of around 6-8 months compared to most of dry grocery having 1-2 years. Since Target is GREAT at sending too much at once and then replenishing when it even starts to sell down, it rarely gets rotated.
Also, doing proper FIFO in areas like that and dairy is extremely difficult with Target's logistic process. In almost every store, the Autofill is scheduled to drop after the truck is acknowledged and PUSH is ran. Since the PUSH application subtracts from the autofill, fresh product off the truck will get sent to the floor while the older stuff located in the backroom stays behind. Short dated items that also sell quickly (yogurt) go out of date all the time because we'll get sent 20 cases of various DPCIs at a time and then get replenished before we can even sell through it. The best you can do is try to check dates while stocking and rotate properly. If you're in backroom and are pulling a case out, make sure that it's the oldest case of that DPCI in the location that is being sent out.
