There's nothing wrong with letting a
healthy flytrap flower! I don't know why people get all worked up about it.
And it's going to flower very soon anyhow, it's already used up most of the energy that the flower requires, so cutting it now wouldn't help much if it were sick. But it's not! It's a very happy plant.
Fly traps in the wild flower like crazy, after all! So so long as they're nice and healthy, it's not hurting anything.

They're very pretty, I'm hoping that shipping and transplant shock doesn't make this one abort the flower, I'd love to see it bloom.
