I've seen that before, can't remember if it's Spanish, Portuguese or central/south American. If its south of the border it's probably crap. The others are OK. The Federal at 5 cents more a 20 round box seems to be a much better deal. What's that, $2.50 more for 1,000? Check the shipping cost, sometimes that eats up the bargain.
Edited:
Ok, so my addition is crappy it's just over $22 more for 1K, still a good price.
