As a Roblox developer, it is currently impossible to create clothing, game passes, etc. and then incentivize said products with proven marketing techniques. All that is at our disposal is advertisement.
There is so much more to marketing though. Sales, coupons, promo-codes, and an array of other smaller features to make the purchase of products more… desirable. Not only that, but it would further the blend between the ROBLOX marketplace and the gaming aspect of ROBLOX.
With things like promo-codes you can accomplish quite a bit. Here is a great example:
You operate a society-style group with a civilian and military aspect, and you would like there to be a military discount on certain options. Solution: Have an in-game vendor that checks the rank of the player in the group, and then that vendor applies a string that you selected to be your promotion code to the in-game purchase- No doubt something random and hard to guess so that your precious military discount is exclusive - and your mission is effectively accomplished.
What does this do in this situation? It incentivizes place revenue, it incentivizes group activity, and it incentivizes marketplace activity.
Normally one would have to advertise a place, advertise a group, and advertise clothing all separately. However with one simple feature - promo codes - you create the potential for so much more if you use it properly.
