The Imps have cut the cost for fans to get into their next home game against Morecambe, and declared the day a fun day for all supporters.
The price of some tickets for the match on 27 September have been cut by more than 80%.
Dave Roberts; speaking to BBC Radio Lincolnshire: "In recent years fans have said that if we reduce our prices we'll attract larger gates.
"This is the perfect opportunity to put this theory into practice. It's now up to the fans to respond."
Admission for the League Two match at Sincil Bank will be £10 for adults down from as much as £17.
Concessions can get in for £5 while under-16s will cost £1.
As well as the cheap admission there will be lots going on from twelve at the ground, bouncy castles, bungee run and a penalty showdown. There will also be football freestyler Dan Magness down at the ground.
Poacher will be out and about this week around local schools this week promoting this initiative.
