When you order from Cue Components, you checkout with their Yahoo Store. Your card is charged, but I don't think that shipping is figured in. Once they fill the order, they resubmit the card. The first charge is just a hold to make sure you have the money. If they were away for a couple of days, the charge may have come back, but when they send it out, they will recharge you. At least that's how I think it works. I've noticed double charges on my card from time to time.
Normally when I order from there, everything arrives fairly quick. There have been a few times that take an extra week or so and I assume they are away or it's just a busy time.
