Are you able to drop off returns here?

Yes with original payment card. Unless they are a PayPal return, you have to send those via mail if you want your money back on your card. If you are ok money back on a gift card, then go ahead and make a return here. This PayPal return policy is located on the Nike website (https://www.nike.com/help/a/how-to-return) which Nike states the following, "Please also note that Nike.com and Nike App orders paid by PayPal will be refunded to a Nike gift card when returned to a store." Don't be fighting with folks ya'll, just be informed beforehand!
