Mailed Experian, using standard postage, no certified or nothing. 35 cents plus cost of two sheets of paper and envelope. Sent 10 disputes on ONE letter. Guess what!! 8 Removals, 1 Update (damn collection) verified, and 1 "creditrust" "in review" ??? what the means. 8 Removals, How much did I spend? The time and effort, plus the paper and envelope and 35 stinking cents. Woohoo. Over 10K in deletions. I now have 2 negatives (creditrust "in review" and 1 collection") thats it on my report. I might now consider negotiating the last $1400 collection to get it off my report in the future. Otherwise i'll wait till 04-2003 when it falls off. I highly recommend using your own disputes, for the first round, before spending any other month. If you would like, i'd be more than glad to post my exact dispute letter sent to experian. All this "send only 3 disputes at a time, send it certified". I think thats overkill.
