Apparently they're an established company in Scotland with an excellent reputation, but I didn't know that at the time. I found them through the internet. I was just browsing through the list of suppliers one day and I noticed their name. I looked them up and found that they had this fantastic discount available that particular month. We ordered various things and the quality was so good we've continued using them.
We like to try out different suppliers to make sure we're always getting the best deal. This particular company was running a big publicity campaign. I'd seen the ads on TV and they really put me off. I just couldn't see the appeal. But then someone I met at a training day told me we should use them. His company had used their service for years with no complaints so we followed his advice.
