i'm currently working on enhancing the purchase flow on a project, and it has been requested to display in-store pricing with the online pricing on products.
any recommendations or examples online that feature in-store pricing?
The answer really depends on what the products are, and your business objectives. I would be wary of using icons on their own - all but a handful of icons can easily be misinterpreted without labels, and can have different meaning in different cultures.
Here are some things that may affect the final outcome:
All of these things could influence the way you display the prices in one way or another. If your goal is to promote the online price over the instore price, then it's best to use clear, unambiguous labels as a starting point. You can support this using different visual treatments - colour, hierarchy, typography or iconography - to emphasise the differences.
In this example, Amazon uses hierarchy and colour to highlight the Kindle version over the printed version of its books. In this, their objectives are apparent - they want to sell a Kindle version over the printed version, and this is clearly reflected in the way the choices are presented to the user.
