Entering email address does NOT subscribe you to any newsletter other than an email notification when a database update is available (paid products only), if you do not want update notifications please tell me to delete you from customer list. For free products I do not send update notifications, you can simply buy again if you need latest version. You can enter fake email address.
Buying more than 1 product? Click BACK, buy the other database, then click Checkout in this page.
Please pay via PayPal whenever is possible! If you do not have a PayPal account you can select PayPal and pay with credit card via PayPal. I added 2Checkout and Credit card in September 2016, use them ONLY when you have no other option. 2Checkout store USD only and if you pay in SGD it takes 5% conversion fee, another $15 fee is taken when I withdraw to my bank account.
AMEX cards may not work with 2checkout, many people reported problems.
Contact me for other payment methods (Skrill, Western Union, Bank Transfer, Bitcoin or other crypto, etc).
