I got mine on eBay from the seller mazaknexus for a good price and they were shipped quickly. The seller has different listings for quantity and "self-gripping" adapters. The regular ones work just fine for me.
Definitely get the jack pad adapters though, since the circular pad on the jack won't fit into the plastic jack pads under the car.
