Fans who pay via credit card will be stung with an extra 2.5 per cent on top, which, using a £372 season ticket for the Telegraph stand as an example, is an extra £9.30.
Prices have also gone up on Iron Cards. If you buy prior to July 31 it will cost £10 adults, and £5 concessions. After July 31 it will be £30 adults and £15 concessions.
Season tickets have also gone up in price by around £20.
Meanwhile, United have announced the introduction of smoke free zones in parts of the stadium after a poll on the official web site showed over 75 per cent would welcome a ban on smoking at Glanford Park.
Smoking is allowed in the Study United terrace, but most parts of the other three stands have been made smoke free.
