I like combining many smaller shipments into one. This helps eliminate errors that come with working on just one large shipment. If I decide to add a few things on after completing a shipment, not a problem. With my shopping and work flow habits, this happens a lot. I save money by combining orders. This alone, pays for the monthly fee.
SellersToolbox is a tremendous value for my business. I use it on a regular basis to help manage my amazon inventory. I use the Bulk Pricing Application for product research and profit analysis on potential buys from wholesalers. It's quick and gives me precise competative pricing information for easy analysis.
I use Seller's Toolbox to save time researching and analyzing my sales data with just a few clicks. The downloadable reports are cleanly formatted and let me work with the data quickly. When I've needed help the support has been fast and accurate. I highly recommend Seller's Toolbox.
SellersToolbox is a very handy tool for Amazon FBA Sellers. Our favorite tool gives us the ability to merge separate FBA shipments into one big shipment. Merging shipments saves you money on shipping costs to the FBA warehouses, since the shipping rate depends on the total weight of a shipment.
I have found the 'close listings tool' alone to be worth the monthly subscription fee. I like to have a good idea of what I have in inventory, and your tool is the best way I know of to deal with closing listings for FBA items that have sold out. It is a definite time saver. The 'merge shipments tool' has been a lifesaver as well. It's helped me out of a couple of pinches that I couldn't have corrected otherwise.
