Total Ripoff! Do not use this site. I got free movie vouchers for giving blood. Went to site and selected a movie and time, printed out the tickets. Easy, right? Well, my wife wanted to change the movie time by 1 hour later (still before the 6 pm evening price change). Atom would let you cancel, and reuse your voucher, BUT, they change the price! It was only 1 hour later than prior tickets, and they increased the price per ticket, and you had to pay out of pocket to use the voucher! Choose another ticket site with real Customer Service policies! This site is a ripoff! I won't give blood again if they are giving out Atom ticket vouchers! I'll go elsewhere, or just not give!! BEWARE!
