So, I had a few stacks of magma blocks and went to go see what they were selling for and they specific shop I want to was selling them for 640r a stack (80 per 8 blocks). Thought that was an oddly high price and asked and someone told me they generally go for 1.75r-2.00r per block, so I'd just like to get a price check on how much a stack of Magma Blocks typically sells for.
They are usually pretty cheap because they are easy to obtain and not in high demand. I would guess not more than 4r/block time value.
