Strafford has pledged that fans buying a season ticket by either June 13 or 30 will receive a Premier League one for the same price should the Owls gain promotion in any of the next three seasons.
He said: "We have been really encouraged by the uptake of season tickets so far this year and I am confident we can hit our target of 16,500, if not exceed it.
"As an extra incentive to join us for what we expect to be a very exciting season ahead, I am delighted we are able to offer all fans who commit to a season ticket by the end of June a guarantee they will be able to buy a Premier League season ticket at 2009/10 Championship prices if we win promotion by 2012.
"I must remind our supporters that season tickets sold this month will go a long way to determining Brian Laws' football budget for the coming season.
"Brian has already made some very positive moves in the transfer market and we want to back him with the ability to bring in more high quality players but that can only happen if we meet our season ticket target."
