Increased Voucher Capability

I was wondering if anyone has written any increased Voucher capability?

I asked my client exactly what functionality he thought he wanted and his response was maybe a limit on the amount of times a particular user might want to use the voucher. I think he's clutching at straws and I'm more than happy to close this off pretty quick in the event that there's nothing out there! :slight_smile:

Ideas welcome (or not) as the case might be. I'm not a retail expert and don't fully understand the implications - or what even he might be eluding to.

Thanks in advance,
