That is one of the problems with selling S/H plants - the cost of shipping. Dry, LECA tends to be roughly twice as dense as bark or CHC. Wet.....hoo-boy.
You also don't know the means of shipping, either. USPS can get pretty pricey, which is why my discount with FedEx Ground & Home Delivery is such a blessing, and this time of year the weather is still uncertain enough to require an expedited service.
