Oh, as for the question, what is my greatest weakness, I was thinking of saying, Although my computer skills aren't the best there are, I do have a basic understanding of how computers and Microsoft work.

I have also been able to teach myself how to burn music to my p.c, and I have also taught myself and some of my friends some basic technical stuff such as how to text, copy and paste, and more. How does that sound?

I doubt that the people there would really care about me not being able to use a computer that well as it's just a cashier job, lol. How does that sound?

As for my strengths, that I have a lot of experience in the field of retail and customer service work, and that I have excellent communication skills, that I'm well organized and detailed oriented, and am able to follow directions well, etc....
