Lowest price guarantee?..

Both Summit and Jegs have a lowest price guarantee..
But who really does?.
Hello Summit I would like to buy X part that you list on sale for $300..
But Jegs sells it for $300 as well..
Will give you a dollar off.. (what a big deal)...
Okay Summit hold that thought..
Hello Jegs.. Summit just said 299..
Hello Summit Jegs just said 298
Hello Jegs Summit just said 297.....
I mean how does this really work? And who has the lowest price guaranteed??..
If I went back and forth on the phone for two hours could I get x part for fifty bucks?..lol..
. Bad planning to buy the cheapest, get a mid priced one. Remember you get what you pay for, but don’t pay too much.
