In addition to date/time based offers.. I would like to have an option to adjust the time when the geo-location offers are sent out by push notifications - so customers won't receive an offer when the venue isn't open. It'd be even better if we can input the venue's google place id and sync the open/close times from GBP.
Also display an offer image if it's persistent on the lock screen. Just a bit of an extra effort to draw customers in!
