saravincent, what you saw was E-Bay adding the postage for each individual item (Say, $5) and then deducting any discount for multiple items (say, $1) because the automated calculator doesn't know how to figure stuffing a bigger envelope or box :D I can tell you that from that seller, I just paid $9.80 shipping for 20 yards of fabric :lol: The seller will combine everything into one invoice, adjust the shipping, then e-mail you the invoice so if you purchase from her don't immediately pay - wait for that e-mailed invoice and all will be fine.
I've placed several orders with her and haven't had any problems.
