ok- i have to laugh at that!
i would like to point out one more thing to anyone who felt they were wrongly charged: visa, amex and i'm pretty sure mc and disc all have a consumer protection policy. if you feel you were screwed, you just return the product and contact the company telling them of it and the merchant will not get paid. it's a little more complicated than that but, from what i see, tzd is still around. if they'd been out to take us all for money, there would have been a lot more bitching going on here.
my own experience with the last sale was that i accidentally submitted an order twice (and the first time was without the '50%' in the order ntoes. i didn't get charged extra, twice or anything else other than what i asked for. just wanted to throw my fair experience into the mix. i hope everything works out for everyone on this.
