Postage is $12.65 for a flat rate box. That includes postage, delivery confirmation and a $1.00 fee for co-op supplies such as bags, tape, and gas to PO, if that is what you mean by fee.
The bulbs are shipped to me and I pack them for individual members. The bulbs are from a bulb broker that imports them and they are kept in cold storage until sold. They don't have a retail site. I've been buying plants and bulbs from them for 6 years for our various co-ops.
If you want to wait until I get the bulbs, I can send you photos.
