I can say proof-positive that Melaleuca cleaning supplies are LESS expensive than going to the store. Almost all of the cleaners are 4X concentrated. That means each bottle really makes 4 bottles. Their laundry detergent is 6X concentrated. Their other products are also more concentrated and less is needed than what you'd typically use in a store-bought brand. You save even more if you buy a pantry pack or another value pack.
Yes, I am a customer, and would like to refer people to the company, but I wouldn't do so unless it was beneficial for them. You can always try it out and get a refund if you're not happy with it. They have a fantastic special on their cleaners that lasts until the end of this month.
You DO pay for shipping, but it's reasonable, and you save in terms of the other benefits a membership offers (including free products,) fewer trips to the store, and for me, lugging detergent and large bottles of vinegar from the car to the house with a 10-month old either screaming in her playyard or hanging on my arm. I also no longer have to do the dance of going to 4 different stores to get the best deal in a given week (better for the environment). One other thing my mom pointed out to me is that because you're not spending as much time at your local superstore, you're cutting WAY down on your impulse buys, most of which are highly caloric, which is a huge savings right there!
Not only that, but these products are MADE IN THE USA and are very effective. Just one example - my MIL used the tub & tile on the rust/iron stains in her shower. She said not only did she not have to scrub at all, but it left a nice shine to the tub as well!
Just a very passionate and satisfied customer!
