Can you share your experience - stores which you SE’d successfully. Will be appreciated

SEed Bestbuy twice, both succeeded.

What's a good reason/excuse to use in case they open the box in front of you? (Let's say you put a different item inside)

I never did it in person because I'm a pussy. I did find some posts on Reddit in which some Bestbuy staff said they always open the box even if they're the only one who does this in the entire store. So I think you should make a legitimate return first to see if they really do this.
