How do you determine your pickup price sheet?

prices here are a lot different in iowa I pay $1complete 50cents incomplete for both towers and laptops. 60clb for single boards 75clb for duel sockets and up for telecom I tried paying higher prices but people were lazy not cleaning boards or would shop around and save up but then get lazy again and sell to me cause they did not want to ship or other silly reasons so I lowered my prices and buy everything for the most part and since then have never run out.
free pickups all the time free drop off in town and I charge for crts and appliances. big thing always answer the phone and always pick up no matter how small factoring in some losses for the bigger picture is cheaper than advertising and face to face kindness
