Not having a go mate honest!
Why can't you price properly @ 4wkly?
I know from experience that a lot of customers will readily agree to the 4wkly, but then comment on how fast the time has gone
I also get the flip side of folk calling after 3 & a bit weeks asking when I'm next due
The point is, if they express the tiniest interest in increasing the time span, that's fine - I just put the price up accordingly and I'm still better off than 6&12 wkly
Everyone's different tho and it depends how busy you are - I couldn't afford to do it methinks
