What is bundling and do I need it?
Bundling is only needed for Amazon orders. It is specifically for 2 things, either you want to sell Add on items, or you don't have a prime account and you need a minimum order to get the free shipping.
If you aren't selling addons, and you have Prime, then you don't need bundling.
Does bundling cost extra?
Bundling costs the same as regular ordering. Each order within the bundle is 10 cents, not each bundle.
If we made each bundle 10 cents then people would hold their orders to try to save a little money.
But doing this would delay orders that otherwise could have been sent out to your buyers sooner.
Also this increases the likelihood of an item going OOS or a price increase. Now you are upset because you'll lose money or you and your buyer are upset because you can't fulfill an order.
How do I enable it?
If you are using bundling for add on items, then also go to Settings > Repricing and choose your source market from the drop down menu; then choose 'Allow "Add-on" offers'
You can choose between $25 bundling which is best for Prime members or you can choose $50 bundling which is for non prime members or Amazon Business purchasing accounts.
