This is what appears on their home page:
"Satisfaction Guaranteed"
"Just pay Shipping"
"30 Day money back guarantee"
"Highly limited risk free trial"
"Claim your risk free full pack of sleep quick strips Now"

They charge you the amount for two packs, despite cancellation within 30 days. They claim that "free trial offer" means that they send you the product, and bill you later anyway"

This is a scam don't fall for it
