"Thank you for doing my HIT with questions about health insurance documents.
I am following up on two things.
1. In addition to the HIT reward, I would like to also offer a $5 Starbucks gift card. You do not need to do anything additional. It is equivalent to what I am giving my in-person participants.
They are physical cards, so I can either send you a gift card card via US mail or I can send you the card number and code via e-mail/mTurk. You will need the Starbucks App or a Starbucks online account to use this e-mailed number.
Please let me know if you would like the card and what your preference for delivery is."
well alrighty then
