Been sticking them up as i see them since feb
One round has had 25% increase, generally the rest are 10 - 20 %
Although one went from 3.50 - 5 which is probably the highest % increase but not an overall killer
Not one problem so far which tells me i have waited too long and they arent high enough so this year will whack them up and next year will knock them into what i would currently canvass them at and that will probably produce a few squirms but i will be happy then , probably just adjust for inflation every 18 - 24 months after that as cant be bothered putting .50 p on every year and £1 a year is probably too much
