Nongnoan, I think it's just a matter of attitude. Different csr got different perspective about how to accept order.
If a csr you dealt with didn't allow you to get free TV, then call them back to get a different csr and tell them that you want to add an item to your existing order. then tell them that you have coupon to use.
unfortunately, I heard that they were out of stock on TV. The only thing you can get for free is the Attache bag........don't know what it is, sorry.
you can always call back to modify your order.
