These lovely scrubs are only £1.95 and I would say you could probably get up to three uses depending on how you use them. I tend to use sugar scrubs on cellulite areas so upper thighs and bum, then as I'd ran out of my foot scrub I used it on them too. I got two uses out of mine but I think I would have been able to get three if I'd split it accordingly before getting in the shower!
The scrub is quite squishy (I'm wanting to say chewy?? Maybe not eat it to find out though...) so you just need to run it under the warm water to get it into a nice paste which you then just rub into your skin.
I have found this a lot more user friendly than my normal Lush Sugar Scrub which I've basically given up on - it's so solid and takes a lot of work to break it down into something which won't take the top layer of your skin off...
