Shipping from USA locations

Was about to place an order for 6 nozzles (weighing just a few ounces) in the Tiertime Store and the shipping from the USA location was $19.72 for UPS Ground, which could take up to a week. There’s not much value in paying that much when USPS can go for $3-8 with faster shipping. Anybody else have this issue with paying way too much for shipping in USA? I ended up ordering from China because it was only $6 (albeit longer time to ship).
