Yes, they do sell your name for mailing. I cannot tell you how many mailings we get, because we reg. give to World Vision and Smile Train. By the way, 94% of your donations go where it is suppose to go for these two charities. I researched it on the comp. We were getting 5-6 mailings, PER DAY!!!!!! No lie! WE had enough carrot seeds to start a farm and all the pennies and nickels. Here is how I stooped all of it. What ever they sent me, I put it all into the postage paid envelope they send you and returned it to them!! Also told them to give the carrot seeds to the countrys that needed them. Believe me, it didn't take long and we no longer receive all the donate letters.
