Estervals is very easy to deal with and has the best prices on HU. The minimum shipping charge to the US is 37.00 Euros but you can order up to 5kg for that. (Depending on what you order, the price can still be equivalent - or cheaper - than tobacco from US sellers that offer free shipping). I have used my credit card without incident and credit cards usually provide the best exchange rate. I have made several orders and have not yet had any issue with customs.
