Hi - just stopped by, do you do this on all items or just that mug? I was thinking of doing this for the same organization - do you have additional info on them, for direct contributions? Thanks!
catkeeper6, You can donate directly to them on their website. (hopefully the post is not removed for a link) here is the link to the donation main page. http://www.aspca.org/site/PageServer?pagename=donate_home It is a good organization and well deserving of help. Others on my list of great ones (and this is no where near all of them) include HSUS, Best Friends, Alley Cat Allies, Alley Cat Rescue, City Critters (NYC)....
In case you did not know, a lot of sellers use mission fish to make donation charity sales. If you sell on eBay you can join mission fish (it is free) and then make a charity sales. You get the special ribbon on the listing and litlists the charity and % they get of the selling amount. I am not sure if you can do a charity search directly on eBay or not, but I think you can from the Mission Fish website at www.missionfish.org.
