I was at SLS in April and I was told that when you pay by credit card it has to be Visa & Mastecard only, and must be issued by a Canadian bank like CIBC, TD etc. it can't be citibank or HSBC.....and I know this is where it gets strange, but, this is what we were told......they charge your credit card US dollars......Luckily I was able to borrow money from a friend and pay her back when we got home
