When crafting magic items, one of the perks is that you get to save 50% of market price.
From the crafting magic items rules
Magic supplies for items are always half of the base price in gp. For many items, the market price equals the base price. Armor, shields, weapons, and items with value independent of their magically enhanced properties add their item cost to the market price. The item cost does not influence the base price (which determines the cost of magic supplies), but it does increase the final market price.
In addition, some items cast or replicate spells with costly material components. For these items, the market price equals the base price plus an extra price for the spell component costs. The cost to create these items is the magic supplies cost plus the costs for the components. Descriptions of these items include an entry that gives the total cost of creating the item.
So from the above its clear that the cost of expensive material components is added to the final market price.
So, as the rules are written (not intended), making this scroll myself would only cost 3062.50 gp, correct? Are there rules elsewhere which prevent this savings?
