I received an offer through "MyPoints" for a site called "UnlockYourLuck". I bid on a Cruise for 2 to the Bahamas & won! I was taken to a page to cashout. My cost was .37, there was a 9.99 transaction fee. They made another offer that I accepted for 19.99. When I checked out, it first said that my card was denied. When I got to the completed screen there was an additional purchase for their bidding tokens for $79.00!!!! & the original card submitted had been charged multiple times. Be AWARE if you get an offer for this site. My bank put a block on my card & then did absolutely NOTHING about the charges! Hopefully these bastages will credit me back. Thank you for letting me vent!
