I went to Amazon first because I am a prime member. Because I was ordering totally on length, I did not have a part number. Sometimes I will search another seller for the part number and then go back to Amazon, but I do not like the way Walmart and Amazon have gained their monopoly. At least Amazon uses small businesses to fill their orders sometimes. I have not been inside a Walmart in over 15 years now. We have 3 Super Walmart's (in a town of 100,000 people) and they had plans to build #4 but canceled it because Texas would not grant them a license to sell Liquor. I do not even drink alcohol at all, but it is not fair to force the local liquor stores out of business. Walmart learned quickly "Don't Mess with Texas".
