We use it for the sale of books in multiple currencies and set it up
the simplest way with different forms for each currency and no actual
shopping cart software (how's that for a cheapo solution!)
I'll be looking at integrating a proper shopping cart as we add a few
more titles -- but we're changing webhosts at the moment and I only
want to worry about one thing at a time.
WorldPay has worked well -- their techs were very supportive in
deciding on initial setups, and as we deal with their Singapore office
there isn't any problem with being in a very different timezone from
the UK.
We set up the email notification so we get two emails on each order --
one the notification of transaction approval, and the other with all
the order details, so we do not have to go to their website very
often.
The only problem in changing from a local merchant account was that we
lost the ability to use Bankcard, which is the old internal Australian
credit card, but not many people use those and I think it has cost us
about one order. And it took a while to arrange for them to take over
our AmEx card approval, but that was almost certainly AmEx fault --
and they were the people we previously rented our terminal from, so it
meant they were going to get less.
WorldPay is a little expensive but I'm sure that the ability to say
that we do not ever see the credit card number gives customers extra
security, and the ability to offer firm prices in three currencies was
the clincher. We are certainly doing more since we changed to them.
There were some problems when they were the subject of a
denial-of-service attack a year or so ago (I don't suppose the virus
writers thought it through that there are a lot of VERY small
businesses using the service) and I think there server has been down
for a couple of hours this year so far, and that was for a planned
upgrade.
