You could also go cheaper still, and this is an especially good offer if you are NOT a club member. They have this stuff (

This means, by $0.97, you can still qualify to use that $15 coupon, and bring it down to 134.97, or less than $6.75/box--NOBODY beats that. How good it is, however, I don't know (Fiocchi, on the other hand, is excellent). It is "American Ammunition" (or "A-Merc")
Yes, you will have to pay shipping, but you do not have to pay sales tax unless you are in their home state of Minnesota, so that saving alone pays half the shipping.
