No, I booked September as it's after Summer and I'm typically out and about less. It was the time that suited me best, where I felt as though it wouldn't be noticed as much.
I believe Dr Mani is upping his prices from £3 a graft to £3.50 as of June (I think this was the date, don't hold me to it). If you secure a booking before this date, pay deposit etc. then you'll be locked into his current prices. This was not used in a way to pressure me into booking any sooner, but more of a heads up. I was told to go away and think about it as much as I liked. So just something else to bear in mind!
