Hey @swoocn, can you give this a review when you get the chance?

Sure thing! Just a heads up - that there will be some merge/ compile-time conflicts as a result of the PR @ #46, especially due to the simplified changes with the SellerType enum. 🙃

Hi @tate1650 - Overall, your initial changes look good to me! Could you please make the necessary re-adjustments once PR #46 is merged? I will be standing by; thanks!

All good, I was anticipating that 😅 and will take care of it

@swoocn Merge conflicts resolved. Wanna take another look? Once this is merged I can deploy all the changes to staging.
