I've seen both waves here in Savannah this weekend, TRU has tons of legendary packs and I know the whereabouts of a few granite crushers, If anyone is in the Sav PM me and I'll share
The TRUs near Lenox, Kennesaw, Cumberland and North Pointe have been very well stocked with wave 1 AND 2 - with the notable exclusion of Lightcore Jet Vac. I've seen every other single and three pack multiple times, but no Jet Vac anywhere.
Walmart by North Pointe and Howell Mill have had a good showings as well, but again, not a trace of Jet Vac.
Other stores - GameStop, Target, Best Buy - have had tons of wave one, with only a hint of wave two here and there. And, you guessed it, no Jet Vac.
It only took two TRU trips, one Walmart trip and one Target trip and I've got all the Giants currently available - except lightcore Jet Vac. Annoying.
