Hi! I was told that because of shipping costs there is no demo program to Puerto Rico (also Hawaii and Alaska). So, why doesn''t TW charge the extra cost of shipping to the client who wants to benefit from the demo program? In terms of receiving and returning items there has never been a problem and I have been buying from TW for at least 5 years. So, I suppose that would also apply to the demo program if it existed in the areas described, including Puerto Rico. Thanks.
