Conclusion

The conclusion is that Meijer is cheaper than Kroger, Walmart, and Marsh. The possible sources of error is that we did not include who had the most sells we included the hard amounts (before sale). Other possible sources would be we look at the wrong price tag or type in something different than want we wanted to type in. Other variables might be: sells, which stores have quantities and want to either get rid of the item. They may be in high demand causing price to get higher or there may not be much demand and want to get lower.
