I used the buyback program at ShopiOSx to sell my Samsung S21 and I had some concerns about receiving payment. After contacting them, they informed me that the inspection process would take approximately 7 days, followed by another 7 days for payment processing. I received the payment on PayPal yesterday currently, their only payout option is PayPal. ShopiOSx inspection team deducted $40 due to some cracks on the phone I sold.
