Since I use this website so much I thought I could help a bit by updating some prices =)
I have a question: I was wondering if it is possible to add the information "components total price" or something like that to the items? It would be so much easier to do the math to find out what to sell to make a good profit.
Please stop adding weird "sales prices". The prices listed on the wiki are the base prises when there is no inflation or deflation (i.e. when the store price levels are at 100 %). That is obviously not the case with the "prices" you're adding. You need to check the item in your inventory and adjust the price to get the base price. So if the inventory price is listed as 60 (-20) or 100 (+20) that means that the correct price without inflation or deflation is 80. That is the figure we are looking for.
I admit that I must have been in the wrong here. I can't for the life of me understand many of the price changes since the new prices seem completely random.
I've been running back and forth between the workshop and A&G's store three times now and everything I could cross check with them gave the same values that you've listed when adjusting to "a no inflation / no deflation" situation.
The price stucture seems to be very random now, but that must be how the devs want it. My apologies for disturbing your work.
