It depends on what ya want but it works out around £34 a week for the shakes alone, tetra is a bit more expensive. I have also been checking it out as the lt pharmacy that i go to is nearly 2 hours away and with my job its not working out as they want me to work around their hours which is annoying. I have an appointment with a cdc next monday as she is fit to see me 9am in the morning and is ten mins down the road. I think the loss is more or less the same but its really for convenience is why I am moving!
