Hi folks,
I use loop & merge to present one voucher out of the 500 codes to each participant for a survey, however I want to avoid presenting the same voucher again for obvious reasons. is there a way where I can present only one voucher and then remove it from the loop & merge column?

Have you looked into quotas?

I don't know why you would use a loop to do this.
The best way to do this if with an external database and a web service so you can keep track of used vouchers.
However, if you want to do something similar to the loop idea, create a multiple choice with all 500 vouchers as choices, then use advanced randomization to show 1 random choice evenly presented.
