Jan, you are welcome. The only reason I know this stuff is every Spring/Summer I have my garden pay for itself thru selling plants. It's a royal pain for the seller to set up but it makes life for a buyer real simple.
Now here is another little gem you may not know. If a seller is selling a bunch of stuff, like Iris Sisters is doing, you might be able to make a deal with them. For instance, say you see three auctions that are expiring soon and none of them have bids. It is worth contacting the seller to see if you can combine all three for not only combined shipping but at a lower price.
