I am one of the folks who had contributed to a thread awhile aback about this. I ended up with $500 worth un activiated. Nightmare..I had purchased online, so they just came chunked into a bag with really no receipt showing the numbers, etc. I had to deal with many, many....many frustrating calls to India, hours wasted, then a try at activating, then that not working, then calling Disney to research and then back to target, etc. After months of this I was finally able to get all but $150 activated, after which even Target gave up and credited my account. Speaking of which I think I may still have a $25 e gift card they sent me since it was such a nightmare. I guess this is easier to fix if you purchase in store since you have a receipt with the numbers, but I vowed to never again buy gift cards from Target. The little savings really wasn't worth it to me in the end.
Oh! looks like it worked out for you. Good news
