As a customer, your right to return an item is exactly the same regardless of whether you've bought the items with an E-Gift card, a debit/credit card, or a combination of the two.
If you've paid for the whole order with an E-Gift card, then a replacement E-Gift card for the amount will be issued to you via email.
If you paid with a combination of debit/credit card and an E-Gift card, we'll refund anything that you paid for on your debit/credit card first, and then the remaining amount will be issued as a new E-Gift card.
E-Gift Cards can only be redeemed in their entirety. If you don't redeem the full cash value of the E-Gift card, then the remaining amount will be forfeited. An E-Gift Card cannot be exchanged for cash.
