I have several auctions of leaves and starter plants up for bid. I will combine shipping. However, -please wait until you are finished bidding, and wait for me to send you an invoice. I will hold your winnings for one additional week if you are bidding on newly listed violets. Ebay does not combine shipping automatically on my auctions. I charge actual cost shipping charges, usually around $7.20. Additional leaves will usually not increase shipping, however, starter plants may increase shipping some.
