The club's current season-ticket holders can now renew online for next season. For a full adult ticket, prices range from £532 to £950.
The club recently dropped out of the top three in the Deloitte football rich list for the first time.
Despite generating a 7% increase in revenue last year, to 423.8m euros (£363m), Real Madrid, Barcelona and Bayern Munich all made more.
Dan Jones, a partner in Deloitte's sports business group, said: "Match-day revenues - of which season ticket sales are the biggest component - have actually been pretty flat across the Premier League.
"For the 2008-09 season, they were £573m and for 2013-14, it's estimated at £580m.
"In real terms that's a fall. The rapid growth in revenues for the clubs have come from broadcast rights and commercial deals."
Manchester United, owned by the US-based Glazer family, will report second-quarter earnings on Wednesday ahead of a vital clash with Arsenal at the Emirates. United's win over The Gunners at Old Trafford was one of the few bright spots in a dismal season and they will be hoping to do the double to try and get their season back on track.
Arsenal also have something to prove after their 5-1 humilaition at the hands of Liverpool last time out.
