Fay I have that happen to me all the time on lots of patterns I buy from other companies, because I live in Spain, however see you are in Washington so she just must have her site set up to do it that way.
Just gone back to look and it says at the top of the page that this pattern is only available through Certified Shops thats why there is no price, all the others have prices on and YES they cost more that 13$ go look at the others they are from around 25$ upwards
