I don't know what you can do except make noise here. I hope it works out.
>...we start getting attention we get payments of $3300 and more.
Thinking of others that may encounter this issue, I wonder if it's possible to spread orders between separate payment processors based on order $ value.
Processor #1: low average order value
Processor #2: high average order value
That way each processor handles orders within 1 standard deviation of the 30 day average (or however you might calculate it). I've never handled inventory for ecommerce. Just wondering.
If that's not possible, should ecommerce sites only ever have a min - max per unit value that isn't too large? e.g. $10 - $100 unit values, with avg $50 orders. Not $10 - $1000 unit values, with avg $50 orders.
