this has always been the case at launches. extremely hard to find a console on it's own and retailers selling bundles only to up their profits, they don't make anything on new consoles but they do on bundles.
iirc i paid like £550+ to get a ps3 at launch as the retailer i ordered from would only sell bundles and the ps3 was impossible to find around launch on it's own nobody was selling them just by themselves. this time it's different retailers are selling them on their own but they are selling out really fast.
now we have the masses shopping on the internet and sites like HUKD, etc it's even harder to buy them because as soon as a deal pops up it's gone within an hour or two.
i got 2 consoles at launch on their own for below £350 because i had ordered 6 months in advance, i then got another one last week for £330. you can get them but they are in short supply imo.
the fact one shop up in the very north has a few doesn't mean much, i doubt you get a major amount of business due to your location and surrounding population so that's why you have stock, demand in your area isn't high most likely, had you been a shop in a major city with plenty of supply then that would be an indicator of no supply issues and supply easily meeting demand.
if you want a ps4 bad enough you can get one easily, if you want one brand new and on it's own, you need to be very quick and constantly looking.
