Watch out! If you can find the T&C read carefully!
Luidaire uses deceptive practices when offering free sample.
They claim hidden terms and conditions require you to return unused product in 14 days or automatically bill you for full ammounts.
In my case they hit my credit card for two swipes at $89.77,
No where during the order process was there indication of a membership enrollment for recurring charges.
During a lengthyargument with customer support they threatened to destroy my credit rating and other veiled threats affecting my finances.
My recommendation stay with OTC avoid on line free offers!
