Something you may want to think about is not having it delivered on a Friday. UPS hubs are not open on Saturdays for pick up, just say the shipment is delayed for any reason, you will not be able to get it till Monday the following week.
Check the weather in Iowa and what it will be here on when it arrives. If Iowa is hot and it is cool here, I would have the shipper put in a couple ice packs with more water in the bag with the anemone (it will help with the temp difference here). Hot weather is a bigger enemy to anemones than cold weather.
