Started with 5 packs for a Panthers F&F and a Myles Australian.
Couldn't help but notice a sealed box sitting right under the opened box on the counter. I decided that this time I would try Wizzle's method by buying 5 packs first and then opening a fresh box.
Bought 12 packs from the fresh box and ended up with a Foran Sig and a Warriors Gold F&F as well as 2 Triples Threats and 2 Australian Reps. Unfortunately I couldn't get back until this morning because I was headed to the Titans game. I searched for that other sig but the boxes has been merged and it looked like several packs were gone. Managed to get every hit from the fresh box accept the Future Sig.
