I ship chips every day(got to pay the rent on this boardwalk store).We use bubble packs via UPS ins.The post office here is a long wait & ups picks up at my door. If something gets lost it only takes 1/2 hour of time to get UPS to pay in 30 days or so. I see a check still waiting to get a reply from the post office on charges I filed agenst Borland on mail BS in 1990ish. So packem well & pray.
