Entering email address does NOT subscribe you to any newsletter other than an email notification when a database update is available (paid products only) unless you ask to be deleted from customers 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.
Contact me for other payment methods (Skrill, Western Union, Bank Transfer, Bitcoin or other crypto, etc).
