[quote name='ShadowAsylum'] That obviously means, they have to be hiding those 2 games in the back or something, since they don't have a clearance display anywhere. That, or someone stole those 2 games.[/QUOTE]
I keep seeing people say that on these forums and I always cringe. So let me offer a couple of reasons for the discrepencies. [Feel free to copy and paste]
Reasons why store inventories may be incorrect:
1. Inventory was counted incorrectly to begin with. There are two ways to electronically inventory items. Sometimes you scan the first bar code and then enter the quanitity on the shelf. Other times (and sometimes is required by the client, especially when dealing with electronics) you have scan each barcode individually. When you're counting 45 of one item, 64 of another, and 70+ of yet another, your mind will wander at some point and you will lose count or miss a scan. Some items get re-counted by a second auditor and random items are recounted to verify an individual auditor's accuracy, but some stuff is just simply going to be miscounted.
2. Some items are confused with other items. In the video game section specifically, a row of games may include Platinum edition or Select or GOTY editions mixed with the "vanilla" or "standard" editions. Usually these items have separate bar codes. So if an auditor goes through a stack and sees 7 copies of Resident Evil 5, they may simply scan the first one and enter a quantity of 7 or pick up the first item (and I've witnessed this) and just scan it 7 times. (Even though this is specifically against policy and defeats the purpose of mandating individual counts!) The auditor doesn't know that the fourth box was actual Resident Evil 5 Gold Edition.
3. An employee rang up the wrong item. This is similar to #2. The cashier picks up two items and thinks they're the same thing. This happened so many times at one my jobs that the company disabled the quantity button on the register.
4. An incoming order has a wrong count and no one catches it. The wrong number gets shipped and the associate stocking shelves doesn't look at the quantity on the box. He opens it up and puts all 5 copies on the shelf without noticing that the side of the package says "quantity:6." Sometimes the quantity of a product is only listed on the invoice.
5. The mistake is caught but is not entered into the inventory control system. I had this actually happen to me. I was running a night shift (when the store computers were offline) and came across a box that was mispicked at the warehouse. Instead of sending us a box of 3 PS1s, the warehouse sent us a box of Matchbox vehicles. When I went back to working days, I found that our count of consoles was off. Sure enough, no one had read my note and entered the discrepency into the computer system.
6. Theft. Like you suggested, sometimes things leave the store in less than ideal ways.
7. There really aren't anything in the back room. I have an amazing visual memory. In 13+ years of grocery/retail I knew almost exactly what was in the stock room/refigerator unit/storage at any given time. If I say it's not in the backroom and I don't offer to look, it's because I know there aren't any in the backroom. Sometimes it's even because I personally was responsible for not ordering enough.
8. It's in the backroom and I know specifically where but I'm not into spelunking. It's going to be a few days before I get to that case against the back wall. If I say "I'm expecting in some at the end of the week," I really mean "I expect to reach that particular case by Friday."
9. There's definitely/possibly some in the back, I know/don't know specifically where, but I either can't leave this register at the moment because there's a line of thirty people behind you/I've gotten the vibe that you're waiting for me to walk away before snatching a handful of stuff/I've had a disagreement with my boss, co-worker, significant other or I don't like you or for some other reason I'm in a foul mood and just don't feel like looking right now. This does happen and it's probably the "I saw you keep looking up here and just don't trust you" reason.
10. They really are holding it for themselves. Despite what a lot of people here seem to think, this is actually the least likely of the possibilities. Most places have strict rules on employees holding items and it's mostly because there just isn't enough room to hold employee purchases.
