Thanks for your thoughts but I am not really questionning my decision to claim the sale price on the custom's forms (I actually already invoiced the buyer before I started this thread for the amount and told them I would be stating the amount on the parcel). I am looking for thoughts on how to handle this with this customer as I am pretty sure that they are not going to be happy. In fact, I have not heard back from them since I invoiced them. I would not be surprised if they did not pay or write me back stating their case. I guess I just have to stand firm and re-iterate my store's policy.
Thanks again for your thoughts and please let me know if anyone else has had to deal with this issue.
