Anecdotally makes sense. Coupons attract scarcity mindset people. If your product targets more time poor money rich growth mindset people, this is a bad fit. My wife has a friend that did every Groupon known to man. She routinely signs up for gyms that have a 30 day special then quits. She says she wants to get in shape but can’t get over her own scarcity mindset to just pay for a regular gym continuously.
She says she wants to get in shape but actually she likes visiting new gyms. Nothing wrong with that, right?
The secret to this stuff is boring - persistent, continuous effort. If you can't even maintain a regular gym membership, you will not get that effort in. She's been complaining for over a decade as she continuous this charade.
