Hey guys,
To make things interesting (OMG, this parachute is a knapsack!), I ordered from three different eBay vendors on the same day, just to track the standard shipping process. The Vifa's come from the US, the Toppings are from two different vendors in China who use different shippers. And the two TP20's are a single shipment, to see how the levies, if any, work out on each consignment. And with my luck, there will be levies! Heavy levies!
Timeline so far, for the edification of future eBay shoppers, or anyone who cares

Will post full timeline after I receive everything.
