I'm very confident someone will buy the club in the time frame. It is a wate of time and effort to do this saveoursaints campaign as there is no chance what so ever it will raise anywhere near the amount it would need in the event of no other buyer coming forward.
Donate cash to the club to help it in the short term until a buyer is found. But as a long term solution to the problems a fan takeover is a complete non starter and won't happen even if there were no other bidders due to the figures required.
