Payment is requested withen 7 days, if you wish longer, please let me know you want to wait for whatever reason, and I will hold the article for payment. I have had trouble getting some overseas mail to my customers so I decided to try UPS only as they had tracking, but I found out that it was too expensive, if the article does not say First Class International or priority , I will mail that way and send you a new invoice when asked.Just mention how you want it mailed to you. and what the price is if you are thinking of buying it, and want to ask a Question. There is available registered mail but quite expensive for small packages under $10, that does not seem worth it. I do try to accommodate my customers, but I have had lost mailings with first class international, as they did not have tracking or insurance. I will still mail first class international if you request it and you take the chance of it not arriving. Sorry that is the best that I can do. Thanks for your patience. If your from Great Britian area or Portugal, the packages are arriving so far.
