Given that I'm outside the contiguous 48 US States I usually ship bigger orders by priority mail. I use flat rate envelopes or boxes and I'm happy to combine shipments, even if they are not ordered together, and refund the extra postage - until the order is shipped. I reuse bubble wrap and packing peanuts as I'm happy to get them off island to keep them out of our landfill. I'm happy to use biodegradable peanuts too as long as I have some, they are also reused, but I prefer to compost those myself. Please let me know if you'd like biodegradable padding.
All domestic orders shipped first class and priority mail are shipped with delivery confirmation. For international orders customs and duties imposed on your end will have to be carried by the customer. Tracking on international orders is only available for Express Mail, so if you would like to upgrade to Express mail, please let me know and I will send you an extra bill for the difference.
