eBay

I won item 390609503208. Does the shipping information mean all items I purchase after this item will be free also when combined? Or is it just this item will stay free when combined?

I have an open case and the seller has twice offered to resend the item, also saying I will recieve it in 10 days. Should I accept the offer to have it resent to me? Will the case automatically be closed then or does paypal keep the case open until I...

My item received was not as described. Is my transaction Id number to be kept private or is it secure to give this information to the seller?
