MRE Depot has canned butter and dry whole eggs in stock. It's really hard right now to find dry whole eggs in stock anywhere, unless it is the hugely expensive Ova Easy kind. But I ordered some eggs last night and they shipped today.
Canned butter is also hard to find in stock, and tends to sell out soon after being received.
