Our flower bed is empty, no soil in it. What soil shall we buy?

[Lovefruitsandvegs]

I have no experience with raised flower beds. We live in a rented house and would like to do something with this flower bed. I do not know which type of soil should I buy? Are there specific types for flowers and vegetables? I have seen Levington grow-bags for vegetables but we would probably need 10 of it to fill in our flower bed. I wanted to fill it in with sand for children but the sand is very expensive. Any suggestions?
Many thanks!

Um, when you say you have a flower bed that is empty what exactly do you mean? does it have a soil base, or a concrete base or paving or something?

The base of the flower bed is just soil but the actual flower bed is empty - there is no soil in it. We could buy bags of play sand for kids or soil for planting flowers. I have seen compost in the shops and grow bags but grow bags look a bit different to normal soil. I understand that I need fresh garden soil but have not seen it in garden centres so may be I should search for it on line.
It looks as it is called topsoil. www.onlinesoil.co.uk/sm4n3.htm

Well, it looks as it is indeed called topsoil but it is very expensive so we would probably have to buy sand instead.
