The Summer Flash Sale is a Prolific promotion running from August 1st 2019 to August 31st 2019. It provides newly registered researchers with a 50% discount on a representative sample study when they meet the eligibility requirements. 
How do I qualify?
  • You must not be an existing Prolific researcher. 
  • You must sign up between August 1st 2019 and August 31st 2019 (BST). 
  • You must top up your account prior to August 31st 2019 (BST). 
How does the discount work?
  • In order to support the recruitment of the niche participant demographics that we need for this service, we charge additional fees for a representative sample. 
  • This promotion provides a 50% discount on those additional representative sample fees. 
  • As an example, with the 50% discount a 500 participant representative sample that runs for 10 minutes would result in $357 in saved fees. 
  • Note that you will still need to pay the regular participant rewards and study fees.
