Thank you! That 5l one with dispenser looks just the ticket.
That's good to know about Home Bargains too, although I do have worries of germy hands picking up bottle to squeeze it. I know I sound like a right worry wart but there are always some nasty bugs around at lambing time, plus we have a lot of children visiting so I think the dispenser may be easier for them to use.
Makro! My dad bought a pack of 12 bottles when ds was born in April 2011. He gave us 6 and we are only half way through one and 1/4 of the way through another! It smells like cucumber though! I don't like it.
