The dollar opened this morning up on Fridays close. At present $1.49170 but has touched $1.495 earlier.
Thomas Exchange currently offering $1.47 and Crown haven't updated yet since Friday, but their current rates look like being pushed up.
Lot of guess work, but will the dollar push the $1.50 mark today? If so I'm guessing you'll be getting $1.55/$1.60 for those wishing to invest with Crown for late Summer.
