Some products are too expensive in the shop, these include basic blocks.

Perhaps a special system can be made:
A discount system: VIPs get 10% off, Veterens(members for a year) get 10% as well.


Things that are quite pricey:
stone brick variants, Ice, snow, bricks, netherstuff.
FFS - flowers.
Name tag- people want to name their pets.
wool, bookshelves and some dyes.
FREAKING EMERALD.
