"get 10% of bucks" (2018)

back in around 2018-2019, there was a model that allowed you to have 10% off from the purchasing on roblox items, by inserting the url link of the particular item in the model. meaning, you'd get some bucks in your account after 2-3 days of doing it. i don't know if it still works, or that it's outdated since roblox has honestly changed alot; if i was you, just don't the process because i feel like it's mostly outdated now and it just wouldn't work. the model in question: https://www.roblox.com/library/522005240/Save-10-on-Anything-you-Buy)
