Any time I have a delivery timing issue I think it is directly related to the size of the order. I haven't used DP since the China bullshit, but would be really suprised if he went scammer - he is a good bro.
I have to say I am grateful that I decided to stock up. Nothing crazy, but I have the next 5 years lined out. It puts my mind at ease, and I love to cuddle with the box.
I would suggest, assuming you have a legit source, stocking up. Prices will only get higher.
