I reached out to DV recently and the latest timeframe for G2 XL Dynastash is at least a month away. They hope July for this specific model, in case anyone else had this question.
I wasn't able to checkout with my cart either, managed to miss all four flash sales. Which is probably a good thing thank you Dynavap for giving us the opportunity to celebrate with you this week! I don't feel bad, I ordered plenty on sale this week so win-win
