Hello,

My store selling some products with physically stocks and redemption vouchers. How to set the redemption card or any apps that can meet my recruitment:

  1. The product is a redemption card, not a Gift card, no cash value inside, just for product redemption.
  2. Let customer to send the redemption vouchers whoever he want.
  3. Allow Buy 5 Get $100 Free Voucher promotion
  4. Allow affiliate code for referral program
  5. Got a QR code feature once the voucher redeem/pickup, mark it as expired automatically

See anyone can give some suggestions to me, thank you!

Cheers,

Patrick
