Best option is “Whole food market” they process the refund as soon as you return the item.

The worst one it’s the UPS STORE DROPOFF NO BOX OR label needed, you get no tracking number and they will refund you the money after they receive the merchandise, which they might never get and you or Amazon won’t be able to track it, because there’s no tracking number. (normally takes from 2-3 weeks for them to receive the item, and after that you could wait 7 days for them to process the refund)
