Personally I think it is usually easier to buy the expensive locked item if it is a store that has a separate checkout inside since it makes the employees who interacted with you trust you and you can carry it around the rest of the store as “I’m a real customer who already spent a lot of money” flag while you nab the easier items.
Buy something cheap on the way out making a show of “I already paid for these ones earlier” with the locked items using the opportunity to pass through the unpaid items. If you somehow get caught you then use the excuse that you got confused about which items you already bought at the first checkout and again insist on fixing your mistake by paying for the ones you missed.
