I got an email last night that Conte is putting several of their plastic and metal sets on sale. These are pretty good prices. A blister card of 8 Mexicans for $6.25. That's about $.78 cents per figure, not a bad price at all. You can amass an army pretty quick at those prices.
Other sets included in the sale are the four sets of Alamo defenders and the 4 sets of Civil War figures. There is a $100 minimum order, but that shouldn't be too hard to justify at these prices. Manage to spend $200, and the shipping is free.
