I need advice with the following matter. The production of my product is almost ready to be shipped to Amazon warehouses from China. There is an option for shipping that takes 25 days, so my product would arrive approximately a week before Christmas, and another that takes more than 30 days, so it would arrive after Christmas and almost New Year’s. The difference between one and the other is almost a thousand dollars.
First, as @AmazonUKForumRefugee says, Amazon will not be able to check on your item that close to Christmas. Take the cheaper option.
Second, have some of the item shipped directly to you. Since this is a first run, quality control is important. Many factories send “great samples” then ship “terrible product.” Plus that gives you FBM sales while you wait for the bulk of the shipment to arrive and get checked in to FBA. (This is also a great plan to ensure inventory between shipments and keeps your sales ranking up and relevant).
It’s too late for you to ship now, so I suggest you choose a cheaper shipping option.
Even if you get it to the Amazon warehouse before Christmas, you won’t be able to get a guarantee that your unit will be processed as “available” on the 25th.
