I normally don't post deals that are huge "YMMV" deals, but hoping someone else can get lucky.
I stopped by my local Target to pick up a gift and they had this LEGO Nexo Knight Knighton Castle on the clearance shelf with a $139.99 price tag. I figured someone just left it there, but just for kicks, I took it to the self-scanner and it came up with "Item not found". So I took it to one of the workers, who turned out to be a "Team Lead", who used her hand-held scanner and it came up as $9.98! Needless to say, I checked the shelf again and there was another one, so yes, I took both of them.
Took it up to the register, told the cashier what the Team Lead told me and she plugged in the price without any issues.
Attached is the pic of the set (does have heavy shelf wear, but can't complain for $10) and receipt.
Hope someone else can get lucky too!
