As for your grey area, comment. We have found that some developers, due to time contraints, do not do a deep dive into how to price their in-store items. Should an item be priced $0.99 or $1.49? Do price points ending in 9's sell better? Great questions.
We also believe players may be interested in receiving notifications if a new item is listed or a price changes in in-app stores.
Hi zainanak! Some friends and I are developing a prototype for gifting/sales of in-game goods and are researching game developer needs to
ensure our platform helps teams like yours. Perhaps we can be of some assistance- we are interested in learning more about what you are looking for in a solution.
