16. Usability Testing 1. You are new to the area. Make sure that Gopher Grocery delivers to your zip code. 2. Your fridge is empty. Locate 3 common items you buy weekly (milk, eggs, & TP) and add them to your shopping cart. 3. You already have eggs. Remove them from shopping cart 4. You forgot the cheese! Find the cheapest block of sharp cheddar cheese and add it to your cart 5. You need to ask the company a question. Locate the contact information

37. Design Claims No manufacturer claims. Instead we find a single customer testimonial “Gopher Grocery's website is fast and clean” Response and loading times are quick; white space keeps site simple and uncluttered.

38. Recommendations Make it more obvious that photos expand Larger item photos Don’t keep organic foods in their own category Adjust search results page Overlapping categories (TP in paper products and bathroom/shower) Larger description text
