I laughed my ass off to this, hahaha
Imagine getting a B-day card with a $5 sprint gift card, thanks grandma!!
I actually got a $200 gift card from Sprint for Christmas. They exist, but there is fine print on those.
I'm not sure if the policy has changed, but at the time of usage, the gift cards can only be sold by and used by corporate-owned Sprint stores. I wrote a huge complaint to Sprint about how the original purchaser and me (the one who redeemed) had no knowing of the fine print and how I wasted 2 hours of my time (as well as the rep's).
Basically what happened was, my fiance bought me the card from a corp Sprint store. I took it to the nearest Sprint store by my house. I got the HTC Hero, they activated it and set it up for me. Then when it came time to pay, I handed him the card. He tried to use it, but couldn't. He called his manager, who then said to call Sprint corp. Sprint corp told him that only the official stores (not 3rd party) could use them. He had to cancel the activations and reactive my old phone. I was in that store for probably 2 hours going through the whole ordeal.
At the time, I didn't even know there was a difference between a 3rd-party Sprint store and a corporate owned Sprint store. Lesson learned.
