I can answer this! Last Christmas someone sent us a big box of stuff from Katz's. The meats (there were 3 or 4) were vacuum packed, and there was some condiments and some bread and I forget what else. It was all packed in a big box with ice packs. I think it was shipped over night from Katz's.

I assume that most deli meats don't lose much being packed up like this? I can't say for sure, but this kind of stuff is probably already served in a similar state, not right out of the oven. So I can only assume it tasted more or less like it would if we have gone to Katz's. The bread no doubt would be better fresh.

It all tasted... ok. I expected it to be awesome, but it was just ok.
