I don't charge extra for shipping on my website, but I don't have the Hokey Pokey pattern. (I've got others!) Some sellers charge a minimun shipping rate so they can use the free Priority flat rate envelopes and not have to pay for additional shipping supplies and it does cost around $5 to mail it, not counting tape, labels, printer ink, time spent packaging, and a trip to the post office. That can really add up $$$ fast. It also makes it more cost effecient to the buyer if the buyer purchases additional items, sometimes the seller won't charge extra S&H if it all fits in the same flat rate envelope.
