Congrats. Looking forward to seeing the pictures.
I live in Massachusetts as well. When I ordered something from the Seattle Nordstrom I had to pay MA tax. I too had thought that if there was not a store in your state, then you do not have to pay sales tax.
There is a store being built in Framingham but it won't be open for business until 2007. I suggest you contact Nordstrom and have the tax refunded. Some s/a's don't know that if there is not a presence of a store in your state you don't have to pay sales tax. It is our job as consumers not to let them convince us that they are right.
