Really - that's true. When we went thru our last hurricane where we were without power for 4 days, we had 3 Coleman coolers filled with ice where we had deli meat, eggs, raw poultry, & such stuff. But really - butter, cheese, vegetables, etc., were just fine in the fridge.
In fact, since we stuffed the fridge freezer with bags of ice, everything in there stayed frozen solid for all 4 days as well.
Not to start a war on market storage, but really - supermarkets aren't always a-okay on their storage procedures either.
I really don't think you'll have any problems.
