Ebay earphones postage?

I want a few of these earphones, cause they're good quality and cheap
from the seller for spares, but if I buy, say, three pairs, will that
times the postage by three?? Check the link for details...

Will it cost me 0.40 x 3 or just 0.40?

Thanks in advance! (im new to ebay!)
