I sell books. On the previous Manage Your Inventory page it was easy to see if another seller was offering the same book at a lower price (and to change your own price if you wanted to) as theinventory page showed the lowest price each book was selling for. The new Manage Your Inventory page does not seem to have this feature, or if does I can't seem to find it. Can anyone enlighten me?

Another Tool That Needs Improvements

No SKUs Available

You cannot search using SKUs on Amazon Seller Central.

Additionally, the bulk upload file does not include a SKU column or even a product description.

Manage Your Sourcing Cost

I noticed that Amazon's estimated values seem random. For example, two identical products (differing only in colour) have estimated costs of £2.51 and £8.94.

When I try to update the cost, Amazon requires proof, meaning I must upload an invoice from the manufacturer showing the purchase price.
