I enjoy collecting, using, trading & giving away coupons of all (vegan-friendly) sorts. My primary source is the Portland Chinook Books: http://www.ecometro.com/portland/default.aspx - so I have many of these coupons available to trade. Many of these are only for use in or near Portland but some are good anywhere in the USA. I also find & use coupons from many other sources as well.
If any of you are interested in trading, receiving or giving away coupons, please get in touch! Also feel free to list which coupons you have or want in this thread. I will list some later.
