Wait... Why do I have to pay for a free sample? Great question. Each sample kit is $5.95 to cover the cost of shipping and packaging for the item. We know that you may want to try our detergents before committing to a full bag, that's why we created sample sizes to let you see the results for yourself. Each sample kit comes with a coupon for $5.95 off of a future order, so your sample kit is basically free!
