Just to add to that, I figure you can get an ROI of about 9% on this, which means payback in 11 days (plus construction time). This is based on doing 15 short recipes and 1 medium recipe per day.

On average, working these stores as hard as you can, they will make a profit of 350k coins per day (using stone cost of 265 per 100) and generate 1.5m XP per day.

On the same basis, the scooter store makes profit of 111k coins and 986k XP per day (20 short recipes and 1 medium one).

So, after you have been paid back, you're making 240k extra coins per day and about 500k extra XP from one of these stores.

If you have land, keep your scooters, of course. Only put them away when you have land constraints.
