<prompt> Human: Hi,Im in my mid twenties with a 9 month old son. My boyfriend and I are wanting to get a membership at either Sams club or Costco. We need some input on which one is the best for our young family. Which one will save us the most? Which one is your favorite and why?  <response>: Costco has higher quality apparel that is more stylish than Sams. Both have great prices. Costco house brands Kirkland are known for their quality.
