Yet another day of bull$stuff at the parts store

I look up all the parts on there web sights because it is full of bad info ,then decide on the right part number I need then supply them with there own part numbers and they still only hit on about 90%,the other 10% is not in there systems. but its the only way to shop in the large urban areas ,where there's 10 people in line all the time.I would guess about 40 % of the people are returning the wrong parts(in hand).if I can ship it I will because standing in line and getting waited on could be 1 hour. so i save that way.
