It's £5 per pic upto 4 pics only at my hosp,
I decided not to buy more than one due to cost at 12 weeks and bless him, he gave me 3.
At 20 week scan I did the same and nope just got the 1 pic - daylight robbery!
It's soooo disgustingly hot, I hope your all managing, I'm finding it all too stressful in the heat, had to buy ice to suck yesterday
