Buying bulk lots from the Wholesaler is NOT a bargain. "Priority Delivery" would be a far more appropriate name. But I do have a question that may end up as a bug. As you can see in the following photo, I already have a Crystal Manufactory, but I want to upgrade it which itself requires Crystal. I was VERY surprised that the Wholesaler was unwilling to sell me any Crystal. Has anybody sorted out the gating, or is it a bug that I need to report?
