Many autoparts store have a formal tool lending program that is structured as buy/return. I know it sounds like @bombcar is suggesting some “lifehack” that is closer to stealing. But, no, this is an actual service provided by actual auto parts stores.
Ok, so they don’t call it a ’buy’ program.
It’s a lending program, for free. With a deposit for full value so it becomes a purchase if you don’t return it in time. Same structure but the phrasing matters.
Cool idea.
If it is a formal policy of the store, then it's a different story. They could also manage it in a way to minimize costs. That said, I have run into people who are proud of "discovering" the lifehack version.
