Yesterday we’ve launched a 50% birthday discount on advertising. Unfortunately, due to my lack of experience configuring our new ecommerce provider, I made a mistake of applying the discount only to the 20,000 impression package. 100k and 250k were shown discounted on the site but were listed at full price on the checkout page.
This is now fixed and I apologize for the confusion this could have caused you. To mitigate this: every buyer of the 100,000 package will get an extra 20,000 impressions free of charge, and every buyer of 250,000 package will get a 40,000 bonus.
Thank you for supporting AdDuplex and sorry for the inconvenience.
