Hi there mcs42,
We understand you have a question about trading in your MacBook and if the value changes after inspection, and we'd like to share a resource that can help.
Check it out here: Apple Trade In
Specifically, take a look at the information below:
"How much will I get for my trade-in?
It depends on the device, model, manufacturer, and condition. Answer a few questions accurately, and once we receive the device within the specified time frame and verify its condition, you’ll most likely receive the full amount of the estimated refund.
Keep in mind that we need to receive your device within 14 days of initiating the trade-in, and the condition needs to match what you told us.
If the condition of the device is different from what you described, we’ll provide a revised value. You can either accept or reject it. If you accept it, we’ll continue with the trade-in and either charge or credit the difference in value to the card you provided. If you reject it, we’ll cancel the trade-in, return your old device, and charge the original trade-in value to your card. No matter what, we’ll send you email updates about the progress of your trade-in, so you’ll know what’s happening at every step."
Cheers!
