Perfect as Compensation for Research Participants
I gave 108 of these to research participants as compensation for participation in a study and they worked well.  There is no charge on shipping and none of the research participants had a problem with their codes working. I also like that there is no charge for the card. If I had bought VISA cards, it would have minimally cost $13.99 for each card,10.00 on the card and $3.99 for purchasing the card, instead of $10.00 for each card.
