We are about to roll out a site to beta testers. The site is a production site and we have tested it using an Authorize.Net Test account, as well as a production account in test mode. In the latter case we encountering errors in Authorize.net transactions saying that the account is in test mode. This is understood and acceptable. However we would like to run for a period of time in full production mode with our beta testers, but we do not want to incur charges. Does anybody have a recommendation as to the best way to do this? Set our pricing at $0.00?
