I think that the quality of the pads are similar... and so are the prices. I suppose it depends on whether youre planning on reselling as a health professional - or using them personally.
To get a competitive price from shuli youll need to become a member, but if youre reselling and like MLM, thats the way to go.
bodypure also sells to health prof, but not multi level. On the flip side, they have more info and seem like a more grounded company (like i said before, i buy from them)
