Hi Tony, There are different backpacks at the department store in the city centre. There are three special offers. The 'Whizz' backpack isn't too bad, but I 'don't think it's the best choice. It isn't big enough. The 'Super' backpack is bigger than the 'Whizz', but in my 2 first the 'Power' backpack is the best. 3 fimally of all, it's big enough for books and a tablet. What's 4 op, noit has a key. 5 more, it's the cheapest backpack.
