Sand for sand pit

[klov]

Hello! Any recommendations as to where to buy sand for a sand pit (preferably online)...cheaply and safely! Homebase / Wickes won't sell it for this purpose!
Thanks

I got mine from a garden centre so you could try one of those instead. however, it's so heavy I wonder what the shipping cost would be!

Most of the supermarkets sell it - Tesco, Asda etc. And Toys R Us.
