In my experience if you have an offer for say 2000 pts for a certain item, you will get 2000 for every item you buy in that one transaction. So..if you buy 1 =2000 pts, if you buy 4 =8000 pts. You are allowed one transaction for those points, ie can't go back the next day buy again and gain any points as the offer expires as soon as you buy one. Hope this helps.
