Yes, there is! The first step is to ensure that you are on the most up to date version of the Oznr app. Older versions of the app likely won't have the filtering feature!
To access the filter feature, when you're on the shop page, click the icon in the upper right-hand corner. It will then pull up different options for you. The default sorting method is by newest content.
Sort Alphabetically
If you want to see the merchants available in your area listed alphabetically, use this option!
Filter by Subscribed Merchants
If you only want to see the merchants to which you are subscribed, this is the filtering option for you!
Keep in mind the following two things when using this filter:
1. It will still follow the sort by option above, so you can filter to show only the venues you're subscribed to, and then sort them by either newest content or alphabetically!
2. If you jump to another city, the same sorting/filtering options you selected carry over to another location. So, if you aren't seeing any offers for another city, check your filtering options!
