every time there is a sale etc on add on item (since it only works/ships with an order of $25 or more) what you do is search for an item thats on pre-order u can type in in the search box pre order and find an item that is only coming out in a few month then once your add on order ships just cancel the pre order
Written better.
Amazon's add-on items are very inexpensive, but they require you to order at least $25 of other items. If you want to get the item shipped by itself,
Just add an unreleased (preorder) item in your purchase and check out. Since Amazon doesn't charge for anything until it ships out, you can get the add-on item now...and cancel the preordered item if you want.
There are caveats to this. First, your conscience might twinge at cancelling the preordered item—but you could just look for upcoming release you do want to buy. Amazon also says that add-on items are cost-prohibitive to ship on their own (i.e., it's not profitable for them). Finally, abuse this too much and Amazon might ban your account.
While it's better to just buy at least $25 of other stuff, if you somehow desperately need cheap markers or household goods and can't think of anything else to buy, this is one way to get it delivered now if you don't mind the above.
