MERCS Miniatures have sold out of many of their recent miniature releases and are awaiting a restock.
From their website:
We are completely out of several miniatures. It hasn’t mattered until today. We thought we might make it to the next resupply (half were restocked this week, the other half next week), but suddenly we had an enormous amount of orders.
Specifically, the CCC, USCR, and MegaCon deals will have to wait until Monday to be fulfilled. If you don’t mind waiting a couple days, go ahead and order. I have already contacted those affected.
