Fantastic Product. Fantastic Service.
DataSprings Dynamic Registration module made it a snap to create a fully customizable web based registration for my site and integrated easily with my Authorize.net account.
What was really amazing to me was that, when I ran into technical issues with my ISP's database server limits, these folks were able to answer my question on what was clearly a DNN / ISP issue and got me back on track.
I can't recommend this product highly enough. Well worth every penny. Saved me thousands of dollars in development costs.
I'll use this on all of my sites going forward.
