Honestly id wager it will definitely happen. They have a £18 product that costs absolutely nothing to make, any business will be eager to profit from that.

As for the players buying them, lets face it most will level in Palace without these and Palace also teaches next to nothing about how a job works.

ive personally not had any issues with these jump potion players, often they just need a bit of guidance through the content. Hopefully there are free companies and fellow players who are eager to help as retaining these players longterm keeps the lights on.
