I sell on
Ebay too.
My listings have the highest shipping. $19.95. This is because I don't use flat rate boxes. I use a 12" X 12" X 8" priority mail box. I stuff it full of wadded paper now that hot weather is here. The large and medium flat rate boxes are not deep enough or wide enough to ship 18 eggs safely in my opinion! Not only that the larger the box the less likely they are to be tossed around potentially harming the eggs! Duck eggs are heavy. I do offer lower shipping (same size box) when I sell small eggs.
It usually costs $17 to ship in this size box, then you add on delivery confirmation, PayPal fees,
Ebay fees (9%), and it takes awhile to wrap the eggs, mark the box, communicate with the buyer, ect.... Rarely do I make $ on shipping!
I refuse to ship in a smaller box because I CARE about the buyer recieving eggs with air sacs intact! I used to refund the difference in actual shipping costs (plus $2.75 to help defray pkging. costs, fees, del. conf., ect...) until
Ebay started charging (9%) on shipping costs in addition to the 9% final value fee, not counting listing fees if you use any of their services! Usually those refunds were $3 or less! Most of the time there was no refund, and sometimes depending on where the package is going it costs more than the listed $19.95 shipping I have listed!
Only on here (BYC) do I still give refunds on the shipping and on eggs that are ordered directly from me! Since I only have to worry about PayPal fees, ect...
I know I personally would rather pay more on shipping to recieve eggs in a large box packaged and marked properly and recieve eggs that have airsacs intact bettering my odds of having a good hatch!
I've recieved eggs in small boxes, med. flat rate, ect.... and there are usually broke eggs, broken air sacs, and semi-loose air sacs that don't make, or if they start making die within a few days! By semi-loose I mean the air sac will stretch half-way down the side of the egg.
