You can definitely create an order with multiple items so you do not need to create a separate order for each item, but we ask that you make sure each item you are sending in is part of a normal BuyBackWorld order so we have a record of everything that you intend to send in and the price we're willing to pay for it so there is no confusion once your order arrives to our facilities.
If you have an additional item that you want to sell and you can't find it on our website, simply submit a Custom Quote and we'll be happy to provide you with a price within 24 hours!
Unfortunately, if you send in extra items that aren't part of your order or our website, we can't guarantee that we will be able to pay you for them and they could end up being recycled so it is always best to create an order with all of the items you are looking to sell.
If you do happen to send in an extra item and there is a value associated with it, we will automatically add that to the final order value of your order, but we will not send you a separate email update regarding that item. You can always email firstname.lastname@example.org to find out the value of your extra item, but remember, to avoid any confusion, it is always best to add all items to your order or submit a Custom Quote for an item you can't locate BEFORE sending in your item(s) so you know upfront what we are willing to pay.
