Is Sam’s Club Worth It?: A Practical Analysis of Club Shopping

In adult life there are many practical questions that require problem solving skills and a little math. This lesson has students figure out the benefits and costs to joining a shopping club like Sam’s Club. Guide your students through a real life case study that requires lots of critical thinking, a little math and the chance to use Excel!

Time Frame: 1 block + homework or 2 blocks


  • 2.6 Demonstrate management of financial resources to meet the goals of individuals and families across the life span.


  • How many of your families shop at wholesale clubs?
  • Do you think wholesale clubs save your family money?
  • How much does it cost to join a club?



  • Computer Lab
  • SMART Board is helpful for instruction & teaching Excel

Background for Teachers:

  • The Smith Case Study is complete in itself with prices already figured out and a simple assumption that each item was purchased 12 times a year.
  • The Bradford Case Study is more complex in that students need to look through the receipts of the family from the past year and create a spreadsheet. They need to actually look up the prices from the internet since they are not given in the worksheet.


  • Depending how bright your students are you can give a lot or a little instruction. I like to have the whole class come up with the generic steps to solving this problem as a group before I send students off in pairs to actually solve the problem.
    • Problem Solving Steps
      1. Figure out what the Smith’s purchase at Sam’s (for the purpose of the analysis only choose items they purchase regularly)
      2. Figure out the quantities of the each item & the unit price (go to to find the items)
      3. Figure out the price of a similar item as Stop & Shop (go to to find items/prices/qty)
      4. Create a spreadsheet (there is one below you can give them as a template)
      5. Get every item in to price per unit subtract the difference (Stop & Shop Unit Price – Sam’s Club Unit Price)
      6. Add the total savings
      7. Multiply by the number of times each item was purchased over the year
  • Demonstrate how to add and multiply in Excel (Again I suggest using a SMART Board)


  • Case Study: The Smiths   or  harder Case Study: The Bradfords


  • An additional activity you can have your students do is a shopping test where they choose 20 items and “shop” (compare prices/qty) at three different stores.
