There services have always been the best in Englewood Florida

I needed a washing machine coupling, a part I've bought in the past from anywhere from 5-10 dollars. He informed me it would be 23 but only 20 if I pay cash. He would not lower price stating he is the only one in town with the part. I order the exact same part he had(brand and all) for 3.57$ online and paid 5$ for overnight shipping. I understand he needs to mark up prices to make money but 600% is unreasonable. I will not shop here again
