Hey Ian,
Good question. I have note used any bulk discount plugins with WooCommerce Tickets and am not sure which one you’re trying, but this one might do the trick:
WooCommerce Bulk Discount
We do offer a full refund on purchases within 30 days, so if bulk discounts don’t seem to be compatible with the plugin and you’d like to return it, you would totally be able to.
Give that a shot and let me know if you have any other questions about ticket discounts–I’d be happy to help as best I can.
Cheers!
Geoff
