Are you(Eden) aware that only one gift card can be purchased without the hassle of resetting the site cookie? I was going to buy a few cards as gifts, and after the first here is the message where the "Add to cart button" is:

Thank you for ordering this item.
It's being shipped now. less

To be fair though, it does that with everything and not just gift cards. I can understand why you'd be frustrated, but at the same time I think it's a nice feature to prevent someone from accidentally buying something twice. You can always call up customer service and manually place a few orders though if you want to order the extra cards before the one you bought gets in. less

"...but at the same time I think it's a nice feature to prevent someone from accidentally buying something twice"

If the system was set up as one click purchases I would agree with you. However, it takes 16 clicks, to complete the purchase of the second gift card. Based on the scenario i described above. less
