Advice on asking employees to check the back etc

I’ve seen a lot of ppl find the good figures this way, how exactly do you go abt this? As much as I love Sonic stuff I also have reallllly bad social anxiety and as autistic as I am I still feel weird being a lone 21 year old asking someone to check for Sonic stuff

I’ve also heard barcodes are important??? Has anyone done this? I really want to just to check if my local target has anything good (and employees seem to be the only way to get neo metal) but I’m scared
