Borrow a mini fridge from a friend or neighbor...

This is what a Buy Nothing group is perfect for if you belong to one.

If you have a Yeti, icepacks in the yeti might work for a week. But you'd need to replenish probably 3x during the week.
I'd just go buy a mini fridge for 100-150 bucks, and then sell it when you don't need it anymore. It would be enough to hold milk, eggs, cheese and other refrigerated items.

Do you have any really good coolers? Or know anyone who does that you can borrow from? We have a serious Yeti cooler and their big ice pack that fits in it and that will keep things cold for days!

Our fridge is broken and park is going to take at least a week to come in. We have 3 little kids so milk, cheese, eggs, condiments etc are staples of their diets. Beyond buying little quantities and shopping often, any tips on making this easier? We do have a working freezer.
