10% (or even 20%) discount on all our programs

Until the end of July August 2013, everyone can get a 10% discount on our programs. Just use the Discount Code SUMMER10POFF in our webshop to get the discount.

Do you want a 20% discount??

Make a donation to the Alzheimer's association (or an Alzheimer's organization in your country) of at least $10 (or Euro) and email me (gert at gdpsoftware dot com) some kind of proof. You will receive a 20% discount code in return for your kindness.

(discounts can not be used with other discount codes)
