If you are ordering during the weekend when they are closed, you can always designate local pickup. Then no shipping cost will be assessed and you can bulk up to your hearts delight over several months.
You will be charge a nominal sales tax but all that will be reimbursed when you request Coolstuff to ship your combined orders for free.
Thanks for the feedback. I may try the local pickup option as that seems the most convenient. Is this confirmed to be acceptable from their perspective?
