Yes, bank accounts for commercial purpose have different fees, but unless they pick a completely stupid bank it's still multiple orders of magnitude cheaper than any other transfer.
Only downside of SEPA is that it is a lot less common outside EU/Europe and then more expensive and instant payment is not really possible (there are some vendors offering solutions ...) but that doesn't seem to be their aim. (Would be: "click here to get a license for a commercial download")
