What is the best approach to showing the difference between wanting to buy and having an item for sale? These options come to mind:
- A filter or sorting menu like list view and thumbnail view;
- Tabs for 'Item for sale' and 'Want to buy';
- A dropdown menu for choosing between categories.
Any suggestions for how I can improve the usability of this? I'm planning to do some A/B testing but I wanted to ask here first.
