PayPal Express refuses transaction when there is an offer on the order.

@maxgarfinkel: Have you extended our default implementation to pass in line item information so that PayPal displays it on their side? To our knowledge, this error only happens if you've extended our OrderToPaymentRequestDTOService to pass in line item information. If you have done this, then that means you also need to take into account any offers or adjustments at that level as well. The PayPal API has their own restriction and checks to make sure the total of the items match the total of the order - their API doesn't allow for passing in Order level adjustments. To account for this, one way is to create another negative line item in your implementation, so that the totals are accounted for. Please reference the README for the PayPal module that talks about this:

See the section entitled: Showing Line Items on PayPal Express's Checkout Screen and scroll to the bottom to see how to account for order level adjustments and possibly fulfillment fees if necessary.
