Not an employee but have a question

I was in my local gamestop yesterday and found a copy of space marine 2 on ps5 marked at 45.99. Obviously im like yo, thats a steal hell yeah, I'm buying it. Well I go up to the counter and guys like oh hey, it's actually 70 bucks. I was like but its marked 45, wym? He's like yeah we must've missed it when we retagged everything and like most stores I was like okay well it's marked at that price so can you honor it? Cuz ya know like alot of stores if they mess up and mark something an incorrect price, they'll honor that price since thats what they marked it. Well dude tells me sorry, corporate won't let me do that anymore, so I can only sell it to you for 70. I asked if there was a manager in cuz that sounded shady, and dude says no manager he was the only one working, which I believe alot of times there's only one employee at this store. But was he bsin me about not.being able to honor the marked price or is gamestop really that hard up for money
