Good subject, I'm new 1 year. I sell 30 a weekend. I sell chips for low prices, and charge 2.00 for shipping and handling. I go to the post office daily, wait 15-20 min. send first class in a bubble mailer, chips are in a plastic zip lock bag. I use a nice address label. Now I could increase the price on the chip 1.00 and only charge 1.00 s&h? Also, e-bay fees are cutting my profit greatly as I only sell 30-35% of what I list. So I feel a little profit on s&h helps with fees. I want to be fair. Thanks for any input. Fred Lamb R-5294 (docschips)
