Yesterday we reported about PS4 Units being back in stock at many Walmart stores across the US, even if the retail chain does not disclose that publicly on their site and store clerks will tell you they don't exist even if you ask.

Since then we've been contacted by Walmart employees confirming the story and offering more details about it.

One employee, working at the receiving department at Walmart (the ones that unload trucks, separate freight, and move it to the sales floor), revealed that the PS4 stock was delivered on the 21st. The electronics department clerk of the store already knew they were coming and had told him to expect them.

Part of the job of our source is to read the codes on the freight delivered to know when to haul it to the sales floor, exactly because some of the items are held back in the storerooms for days or even weeks in order to match sales.

All the PS4 delivered had the USA code, which corresponds to Black Friday, and there are four different USA codes, corresponding to 8 PM, 10 PM (on Thanksgiving), Midnight and 6 AM.

A second employee, of the Store Manager level, confirmed the delivery as well on the same day, and mentioned that those PS4 are strictly held back until Black Friday simply because the flyers already distributed announced that the consoles will be in stock, so stores have to stockpile in order to match what advertised to the customers.

So there you have it. If you want a PS4 (or Xbox One) on Thanksgiving or Black Friday and you plan to shop at Walmart, the times mentioned above are the ones that will offer the best chance to find your coveted console. Good luck with that. You'll need it.
