For the auction price, it just will same "USD 19". A currency symbol and decimals would make it much more clear.. for example "USD $19.00". Same goes for the "Enter 20.5 or more".. it should be "Enter $20.50 or more". Also, I have it set for only US, and it still says "ships to US & many other countries", even though I have it just set for US.
Thanks! Here is a link to one of my auctions:
