Giftedk , i just put up all my prices over the last month , £1 is ok but if i were you i would go for at least £2 , my rises were mostly £1 , some 2,3,5 , i got one grumble from a 5 year est round , i had not put up in 5 years and i now wish i had done em all for £2 at least , i did not lose one custy.
Only you know your round and what they will stomach , but take it from me , i would rather hit them bigger once than twice in a row !
If your not sure do it a street at a time to test the water , that way your in full control of any losses you may incur .
No expert , just saying my piece .
Regards Rich
