 * Hi,
 * we are experiencing a rather curious bug with PayPal, where SOME bundle configurations
   can’t be checked out due to the “CANNOT_BE_NEGATIVE” error showing up when customers
   try to check out.
 * I haven’t been able to figure out what exactly causes this error, especially 
   since there is no discount set at all, each item gets added to the bundle at 
   full price.
 * PayPal is the only payment method, so it is crucial that it works with the bundle
   Plugin…
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fpaypal-error-cannot_be_negative%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * For example, a customer tried to check out
    - 3 Personen (2x)
    - Käsevariation (1x)
    - Wurstvariation (1x)
    - Nutella (1x)
 * with a total of 111€ and the error then showed up when they tried to check the
   order out (that’s how we got notified about the error message)

 * Hi [@accudoramona](https://wordpress.org/support/users/accudoramona/) ,
 * FYI, this error was caused in some payment plugins since our plugin uses a negative
   amount to offer discounts for smart bundles. So if your bundles are using the
   fixed total price or auto-priced method but with an amount discount, there will
   be errors like this.
 * Unfortunately, we can’t provide any fix or solution to this as it’s the basic
   mechanism of pricing and discount in our plugin.
 * Instead, you can try to configure the auto-priced bundles with a percentage discount
   or offering coupons/vouchers when it comes to amount discount for bundles. Or
   you can kindly consider some other alternative payment plugins/methods for your
   site.
 * Best regards.

 * Hi [@janilyn409](https://wordpress.org/support/users/janilyn409/),
 * thank you for your reply. In the meantime, we have slightly altered the bundling-
   process by avoiding 0€ amounts entirely and were able to “fix” the error – thank
   you anyway!

 * Hi, I tried to configure the auto-priced bundles with a percentage discount but
   it doesn’t work either. Do you have a step by step explanation for that, to be
   sure I understand correctly. Thanks a lot in advance
