Yes, you can. In the future, you can always check by going to checkout and seeing if the No-Rush credit is applied to the total. Generally, most items sold by Amazon Digital Services are eligible for No-Rush credit.

Yup, you can get all sorts of digital gift cards with them. Make sure to double check at the checkout just in case though. Sometimes a physical card gets mixed in and those aren't covered.

Someone mentioned on here that they were able to get games with promo points. Does anyone know if you can get digital PS store digital cards or plus cards with the promo codes (the delayed shipping $1 promo credits) I have enough to get my son a one-year card, but since I have them all from free products, I'd rather not chat with Amazon and raise any flags :)  Thanks!
