It currently costs over $110 to get a single version of all the content on the cash shop.

If you mean the different stone and log types, those are functional gameplay elements - those weren't added for aesthetics primarily. We added new block forms every now and then and decorative items that fit a specific new feature theme and plan to do that going forward as well, but there was no plans to introduce any cosmetic items without a gameplay based reason.

Originally posted by Afrozzi: What is different about them from a functional standpoint? Let's use Mortared Stone. All cosmetic variations are used for the same recipes as the original. The default unskinned version still exists and can be crafted with same cost.

Do you refer to the different stone types? They're all part of world generation, have different traits and spawn in different biomes, quantities and contain different ores. Their reason of implementation is that, not the color they offer. Before those were introduced we had generic blueish stone everywhere as a placeholder.
