If you will notice the SaleHoo listed suppliers offer the crystals, as the Swarovski company does not sell these crystals directly to the end user. The suppliers get them at huge volume discounts, and then pass the savings on to you as a reseller, OR you may choose to go directly to the mother company.
In my recent post about getting the products directly from Swarovski I was referring to the jewelry, pens, keyholders, mobile accessories etc I saw from the link Link hidden: Login to view which I thought you were specifically after.
As I have mentioned, with the increasing popularity of Swarovski crystal products and the steadily growing market, Swarovski is looking to open new, independent Swarovski Partner Boutiques.
Hope this helps. :)
