I believe this is a bug and not just me but I thought I would throw this out there. I was just playing around the checkout. Here's what's going on:
1. No comma in the quantity
2. 2 Shipping & Handling Lines (1 TBD and the 1 $0.00). Once you select a shipping method, only one line remains.
3. No comma in the tax
4. No comma in the order total
That's a screenshot to the issues. I don't get orders like that, I doubt many do, but I was playing around. Anyway, here's hoping.
Edit: I forgot to include. I'm on 0.70.
