That's novel Jess!
We have one like that not too far from us. http://www.homeleighonline.co.uk/ although I couldn't honestly say if they sold pregnancy tests, they seem to have everything else. It's become almost an outing destination, lots of coach parties seem to have a stop off there.
Mr P goes there to buy his tropical fish food (and the odd fish when budget allows) I always pop in to say hello to the macaw and have a browse round the home section. The display they put on at Christmas with moving polar bears, reindeer etc is wonderful, they also have a member of staff hidden away with a microphone, who chats to the children as they are going down the stairs into the Christmas department. The looks on some of their little faces is priceless!
Although the actual plant section seems to be a bit smaller than it used to be, I must say the staff are very knowledgeable, and some of them specialise in particular types of plants.
