Been watching the Walmart vs. Amazon price war on the PW31 since the start of this month and $244.50 is the lowest price it has ever been with local pickup. Price has remained stagnant for 4 days, but I did not pull the trigger until a few minutes ago hoping it would go lower. However, just now, the Amazon price bounced back to a high of $304 (also the Home Depot price). Watching other WEN price wars, I learned that if Amazon stays at this price for at least one cycle, Walmart will likely bounce its price as well.
The same trend has been happening to the weaker/cheaper version of this product, the PW28. However, for $27 more, it made sense for me to go for the PW31 which pumps out 2.5GPM @ 3100PSI via a 208cc OHV engine.
