iOS Promo Codes In Exchange For Retweets (SaaS)

Reviews
Discussion
Thoughts: • The first campaign is free and the first five retweets are free. • A bit pricey, but cheaper and likely more effective than buying ads. * The users have to follow you to receive the DM with your promo code. Overall, it's a tool that didn't exist before that sounds fruitful. Reminds me of http://www.paywithatweet.com/
This has similarities to Thunderclap although this feels a bit disingenuous without disclosing the fact that you're getting compensated for the tweet.
