I personally have had great luck with Harbour Freight blades, I always go get some when I'm in the US. I've never had them shipped to me so I can't speak to that.
In the 10+ years I've been using them, I have only once had one that wasn't good.
As an alternative, maybe ask for on line purchase options from board members (i.e. other sources) - I know some people have a favourite retailer where they bulk buy something like 100 or 50, and they are quite happy with their blades they order.
