Where best to buy walking equipment?

[ben]

I am struggling to find a place that sells a clear range of equipment for walkers. I am interested in a walking cane, map holder, the boot covers etc. but i can't find these things in my local town. So because i can't touch them and i really don't want to drive any distance for these things, i suppose i am limited to an internet puchase- any ideas?

Thanks, Ben
