Do people see the price you actually put or the tax-inclusive price?

Only the tax included price, which is shown on the dialogue you put your price on.

@coldreactive So if I set the price to 16,000,000 and the tax-inclusive price turns out to be 16,800,000, they see the 16,800,000 one, correct??

Yes, they do see the 16,800,000 in that case.

@coldreactive Thank you so much!
