If you are considering purchasing Bare Minerals on Ebay, always look at the size of the item being sold.  Many items listed on Ebay are an 1/8 of a teaspoon sample; you don't want to bid on that like it is a full 2 gram jar.  And with different people listing in teaspoons, grams and ounces, it can all get pretty confusing.  Look on Bare Mineral's website to see the amounts of full sizes versus samples and then use a conversion calculator to help you determine exactly how much product is up for sale.  (A great conversion calculator can be found at the Gourmet Sleuth website).  On a couple of my first Ebay Bare Minerals purchases, I actually paid more for less product, oops!  If you are trying the product or a shade for the first time, purchasing a sample is a good idea. Finally, try to find a seller who has lots of product available and who offers shipping discounts or combined shipping since this is the type of product you will probably return to Ebay to buy again and again!
