Not as often as I used to, up to 4-5 yrs ago usually 3-4 times per month, reducing gradually, these days down to 1, sometimes 2 per month, v occasionally 3 if £ available/urge is there, or sometimes 0!
3 punts so far this year, 19 in 2015, 22 in 2014 and so on..., bit less than 35-45 per year back then!
Not getting any younger, have also tended to stick with/rotate 2-3 "regulars" last couple of years, occasional market research of new girls but had a few so so's last year so have got a bit selective, altho quite a few on AW I would like to investigate eventually!
