I don't know If any of you had a similar situation to this one,
but I really need help as this could be a way to get a Nspire CAS Cx.

I bought two calculators at http://underwooddistributing.com/

And then they when they site calculated the shipment it said it would be $3 (usd) for bringing it here [Brazil].

Then, I got this e-mail today:

My question is: If their site made this calculation wrong isn't their problem and they should give me the product, or they may not sell this to me?


Because I feel cheated by this whole system.


Sometime ago, I bought a book from a danish site, and it made the shipment calculation wrong too,
but they assumed it was their error, corrected their site, and send me the product.

So I was wondering how does this work on the USA...


Can anyone help me?
