>This is an advantage to using a credit card. You have the power of the CC company behind you, since CC merchants must abide by certian rules.

Rules - those aren't rules. Client says - I don't want this. CC Company
says OK and the vendor gets a chargeback. Not fun if you are a merchant <s>...

I've had some problems with this myself. I've had a few people just cancel
their charges after they've purchased software. Since the merchant can't
dispute the cancel there's very little the merchant can do. The CC company
just says, sorry they cancelled and that's that. All you can do at that
point is sue the customer which is hardly ever worth it...

While I can understand legit claims happen there's also the bad potential
on the other end.

I think the whole issue with SE seems to be the bad strategy of not
having demos. I believe in try before you buy - if vendors don't
have something to look at - that's highly suspicious.

FWIW, I use shareware and then have no refunds after purchase since
products can be demo'd beforehand. This makes much more sense to me
both from a customer satisfaction and business model perspective.
