Camille,
I noticed something about shipping to Alaska and using a purchase order on the Rainbow Resource website (I changed the text to red to highlight for you; Rainbow bolded the last line):

How long will it take to receive my order?
Normally, your order will leave our warehouse from one to six business days after we receive it. If all items on your order are in stock, it may go out the next day, especially during times of the year when our order volume is relatively low. If there are items on your order that are temporarily out of stock, we hold the order up to 5 business days to try to fulfill the out of stock items. School purchase orders may be held up to 10 business days to fulfill out of stock items. Please see our backorders policy for more information on how these are handled.
During April, May, June and July we are packing for exhibits at our warehouse, and this sometimes slows shipping time. The heavy order volume we experience in July, August, and September can also slow shipping time, although we are constantly implementing measures to improve our order processing time.
If your order is shipping UPS, actual shipping time (after it leaves our warehouse) varies from 1-7 days, depending on the shipping zone in which you are located. Orders shipped U.S. Postal Service Media Mail (Book Rate) may take up to 2-4 weeks within the 48 contiguous states. U.S. Postal Service shipments to AK and HI may take up to 3-5 weeks, while USPS Priority Mail shipments to AK and HI generally take 5-7 days. Please allow 2-3 weeks for Canada Air Mail, and 4-6 weeks for shipments sent Air Mail to other countries. We are not able to provide shipping time estimates on orders shipped to APO addresses. If order processing time is important, please order by phone during our normal business hours so that we can give you our best shipping time estimate.

God bless,
