Can I show both my wholesale and retail pricing?

Definitely! First create your first item showing your retail pricing (for example) and the appropriate pricing and quantities (e.g. “Ea” or “dozen,” etc.) for that. Then use the “Create a duplicate of this item” button to create a duplicate. Then rename the duplicate (e.g. as “bulk” or “wholesale”) for your wholesale pricing and show the appropriate pricing and quantities (e.g. “20-lb” etc.) for that item. Please see this video for a very brief tutorial.
