Where, other than partsexpress, is a good place to get these? I'm not happy with partsexpress. Their site gave me a shipping quote of 4.90 first class or 6.50 priority for an order of 6 caps. When I was checking out and got to the shipping options, it had the USPS greyed out and the cheapest option was UPS ground for 10.80. That's more money and longer transit time. These caps can't weigh more than 8oz (1uf and 5uf caps).
