@zimmer-media I do use TB on 2 live sites that bring in a lot of money, one of them over $100k, they work way better than with PS 1.6. I will be adding a 3rd site within the next few months. Prior to TB I was planning on ditching PS for WP. Both use PayPal one uses a paid module from presto-changeo, the higher grossing site actually uses the TB integrated module.
Look what it comes down to for me is I have almost never been able to get help in the PS forums when I had issues so any help found here is already 100% better, I always had to figure it out my self with PS. If I was having the issue you were paying for 2 hours of support is what I would do without question. I really can't believe that the cost of switching platforms is less than the cost of 2 or even 5 hours of paid support.
I would also note I am not really a developer but do contribute back on Patreon.
