I have recently combined all of my eBay stores into one store. This is now are only eBay store. This will allow me to focus on a more diverse selection of products in one location.
I buy Jewelry from the largest online retailers of jewelry. These items range from return goods, excess inventory or one of a kind that the largest online retailers no longer choose to offer.
Most online stores show a list or MSRP price and then a major discount often as much as 80%.
I believe that the MSRP although impressive represents a cost that is highly inflated to make it appear that the customer is getting a greatly discounted price.
I take each item and identify what the true selling price including freight was from online retailers. I then discount the item 25% to 40% below the online retailers true selling price.
