XMAS SHOPPING By Martin Scanlan Martin is visually impaired. Shopping, in the shops, has become a bit of an access issue. The crowds make things challenging, the shops are difficult to navigate around, the labels on the products are too small to read unaided and let's not even mention store detectives. Things are even worse at Christmas time. Because of this, Martin is doing most of his Christmas shopping this year on the internet, where he can magnify the information, navigate around easily and not get bumped into.
