In Splendor, when I buy a development card, can I choose to pay the full price using coins, rather than exploiting the bonus price reduction given by the development cards I already own?
Example: I have 3 emerald resources, and 3 emerald coins. On the board, there are no development cards with a price of more than 3 emeralds. Can I buy one of those using my coins rather than exploiting the three cards I already own?
This happened during a game in which I miscounted my opponent's resources and she took a card worth 6 emeralds which I was after. In a later game phase, I was in the situation of having to get rid of the excess emeralds to free room for other gem coins I needed.
