I haven’t seen this question before, but we can’t be the only winery struggling with this.
We give members complimentary tastings. Unfortunately members don’t always leave tips for these tastings (bummer). So we’d like to be able to ring up the sale (which I’ve set up to zero-out for members) and be able to show the Tip line and have the member put the tip on their CC and sign. This accomplishes two things: 1. allows tips on CC, and 2. Shows the member the value of their tastings.
Right now because the charge is $0 it won’t offer the credit card signature screen with the tip line. Any ideas for how to do this? A creative work around?
