Same problem here. I had no idea there was such limit.
Recently my site started providing free membership to monthly eZine and podcasts. Members are pouring in right now at a rate of about 10 per hour, and we're about to hit the maximum. Hope you guys get a chance to extend my limit of 100 free checkouts in time.
What's a long-term solution to circumvent this problem next time? I want to send links and uploads to my members for free, and create a database where I can send direct emails out whenever a new product arrives. What would you do, and is e-junkie really a good place for me to be trying to run my business in this manner, which, by the way, is working out phenomenally well?
