This is true, and if I was prepared to use amazon (or the like) it might be possible.
But really I’d just like Lego to not be scummy and sell the minifigs as official sets, then I would be prepared to spend more money
Edit: also I have it on fairly good authority (a lego enthusiast working in a supermarket) that a lot of people just camped out in the aisle and groped the minifig bags till they identified the distinguishing pieces.
And my kid’s pretty amazing otherwise with temptation. We can pass all the sweets and cookies without any comments, but those minifig stands are catnip!
