O' Reilly Auto Parts May have added $10 to cost of auto part when realizing I was concerned about getting a ticket for brake light problem Blue Springs, Missouri

Went in to O'Reilly Auto Parts, Hwy 7, Blue Springs, MO to get a brake light switch for a 98 Ford Escort. Was a little frustrated since I had to drive the Escort there with the brake lights not working properly and mentioned my concern and that I did not want to drive any further than I had to in order to get the part for traffic safety reasons and of course the possibility of getting a ticket and car towed. The person ordering the part for me rubbed his hands together and smiled a big smile when I asked the price: $35 (and change). Got home and called Advance Auto Parts, Blue Springs, MO. The price of the same part is $26.79. I have never compared pricing on these two businesses before. But I am very suspicious when I realized near $10 difference in price and wonder if the guy at O'Reilly jacked up the price thinking I would not go anywhere else. So I called O'Reilly to cancel the order and told them I found it for $10 less at Advance Auto Parts, the O'Reilly employee did not offer any discount on their part, and when I said: 'thanks for trying to rip me off', he said: 'not a problem'.
