Can i use walmart egift for buy some another egift in walmart ?
in most cases yes. if I buy a code from someone else I either print it and run to the store straight away or I buy another egift code with their code. you should also be able to buy any other retailer's gift card at the stores or online shipping is required if physical otherwise it should be emailed. you can not purchase prepaid debits or visa/mastercard gift cards
at the self checkout. But visa I can't buy with a walmart gift card, period.
