Last night saw the release of BuyPlayTix 4.10 which contains many bug fixes and performance improvements. As always the full release notes can be found here.
But there are two big new features.
BuyPlayTix has had Season Passes and Festival Passes. But both of those are tied to one person getting a ticket to a list of shows.
A Punchcard Pass on the other hand is a block of discounted tickets. The patron buys the pass which has a set number of punches (say 6). They can then use that pass to buy 2 tickets for each show of the season, or use it to buy 6 tickets to one show.
Passes are a feature that has to be enabled in BuyPlayTix. To do so choose Settings. Then click on Global Settings. Choose the Sales tab. Check the Passes checkbox, and click Save Changes.
Combos are my second attempt to solve the problem of selling double-bills (and it may not be the last). With a combo you can set a group of shows to be grouped together under one price. Combos can be grouped across productions. The price will show up in the cart with the tickets grouped.
To setup a combo look for the new combo icon on the Production page.
