Dahon Mu P8 Clip on or fixed basket

[Jason]

Hope you good folk can help us with the above, now the folder lives in doors by the front door, Mrs Bourne wants a basket to carry small items from the shops. Clip on/off or fixed will suitable.
It has a rear rack, but we are not sure of what to purchase?

I'd get pretty much any rigid basket, drill some slots in the bottom at the right place (make sure it's far enough back not to get kicked) and strap it to the rear rack with plant ties or - if you want to look nicer and probably be more secure - bike basket straps (£2.50 a pair at a local shop). Drop a floppy shopping bag into it with handles tied together to stop small stuff bouncing out as you ride.
