so if i bought a lot og them would it charge me for the delivery of 1 book or the delivery of all the books i purchased for a penny each
Depends if you buy them all from the same seller. If you did, then they'd probably deliver them all together.
No - you'd usually pay full postage for each item. Because obviously if you buy ten books its going to cost the seller a lot more in postage than one book would.
Although some sellers offer price/delivery reductions for each additional item you order from them. They'll say on the listing if they do this.
These books, they aren't eBooks, but real printed paper ones, right?
