We look at when you first activated your device in the Birdfy app to determine your usage period, not when you created your Birdfy account. For example, if you activated your Birdfy device 2 years ago, but created your account 3 years ago, your usage period will be 2 years.

This happens because there's a minimum purchase amount required ($100/$200/$300) depending on which coupon you have. Check the Renew Credit chart to see what minimum amount applies to your coupon. Don't worry - your coupon won't be used until you successfully complete checkout.

Yes, absolutely! Any product can count toward the minimum amount, as long as there's one new product in your cart.
