Here’s what consumers have asked with answers from EagleSaver.com staff and previous consumers.
I would recommend splitting them up and shipping them out on separate trade-in orders, unless you can pack all 200 CDs in one box and that the box weighs less than 50 pounds. Just keep in mind that not every single CD you are trying to sell to them will be accepted. There is a good chance that some of them will get you a "We are not currently accepting this item" message instead of a trade-in value.
