Sure you're technically getting more than the standard price worth of items, but that's the equivalent of $50 in diamonds. I have to imagine there will be much more worthwhile purchases in the time it would take you to recoup that amount. Biscuits tend to go pretty fast, so it never seems too worth for me to exchange diamonds for them.
