Most of these sites require you to register with them to create accounts and it is 1 account per address. If you are wondering how other couponers get multiple copies of coupons, we generally use our friends and family addresses to create accounts and then get them to give us the envelopes of coupons when they arrive.
For printable coupons, some sites only allow you to print 2 copies per coupon per IP address, while other sites only allow 1 print per coupon per account within a certain amount of time. Lots of printable and mailable coupons will be available for order again after a certain amount of time has past, so always keep an eye on websites for coupons to pop back up again.
These coupons are sometimes store specific so always double check to make sure they are a manufacturer coupon, and not a store coupon before using it outside the store.
The next kind of coupon are insert coupons. These are found usually with your local paper, flyers or subcribed to newspaper.
These inserts usually contain a variety of coupons that you can cut out and use. If you want to get a bunch of these, you can find extras in the recycle bins of neighbours on garage night, in charity paper bins at churches or schools (just be careful and don't get caught) or for trade on various couponing sites. Also it doesn't hurt to ask friends or family to collect them for you if they don't use them.
Another way to get coupons is to write or call companies about their products or directly request coupons from companies. Companies like Johnson & Johnson, Kimberly-Clark, Colgate-Palmolive, Chapman's Ice Cream are great examples of companies that love to send out coupons to their customers when you call or email them.
Smart Canucks has a great list of companies you can contact with their contact info.
Finally you can also find coupons in free samples, on products in the stores (peelies), in packages or in magazines or free promotional calenders. Coupons can be found in various places and I tend to keep all the ones I find in a binder with baseball card inserts to organize them. The more you find, the more you need a good place to put them. And I never throw any away because you never know what will make a free item one day or a money maker deal, and I have used many a free item as trade for items I did need.
