Twice I've got 12 mouse traps from Amazon. Each time it's been a different vendor (not Amazon.) Literally 20 minutes ago I just checked the mailbox, and there was a padded envelope in it - my latest (third) order of mouse traps, from a third vendor. Inside the envelope? ONE mouse trap.

Sorry, anecdote and vent. But yes, we need verified vendors that actually ship you what you order.

(I'll be a good boy and pick up mouse traps from Home Depot. I've learned my lesson the hard way.)
