The verbal information that Morrisons uses are the conversations you have with the employees in the stores. When you ask them about product information they should be able to give you information about the product. When the employees give the information you were looking for you are more likely to buy it.
Morrisons has their own paper/magazine where they list the newest deals, which you can get by signing up in the shops. With this they hope to get people interested in the deals and lure you into the shop.
Morrisons has their own website where there can be found a lot of written on-screen information. For example there is a page about the fresh meat sales because of the horse meat ‘scandal’. On the page they are talking about that the meat from the fresh meat counter is 100% British meat from British slaughters, British people are happy about this because they are against eating horse meat.
Morrisons has commercials running in the UK to inform people about the newest deals that you can get in the shops. They now have a few commercials running about the Morrisons’ slaughters and fishers to insure you that it is 100% British.
All the commercials that Morrisons run on TV are also put up onto Youtube on their own Youtube-channel. On this channel you can rewatch the commercials but also look up older ones if you are interested in that.
