Building Sand 3 bags (Central Crouch End N8)

Standard size Travis Perkins Building Sand. 3 bags, of which 2 are opened but almost full, with sand in good condition. Probably c.25kg each. There's a separate black-plastic bag half full too.
Here's a link to the T. Perkins website showing the same TP996239 bag with a slightly different printing:

They need to be picked up ASAP because if not wanted they'll be taken to the dump.
