Heat/cold pack at this time of year?

Shipping from Memphis, TN to Los Angeles, CA - Would I need a heat or cold pack during this time of the year? It's quite comfortable where I am now - not sure about LA tho.

If its 70+ no heat pack is required.

It's good to check weather of where you're shipping to so you do know. If it's between 70-85 I usually don't use anything. If its cooler I use a heat pack, if its much warmer I'll use a cool pack.

You may want to check the route the package will take. It could go up north before making the trip west. It can still get cold. I know that it was 86 degrees today in Maryland, but tomorrow it's not going to get above 60. This time of year the temps can very day by day, hour by hour for that matter.

Good Luck!
