Any customizations result in a different line item on the invoice and make the coupon code box disappear at checkout.
No response for 8 days to my ticket. Please advise!!
Did you ever solve this?
Yes - due to them using the draft API, options appear as a second line item; nothing can be done about that but the coupon code box issue is linked to the options and their display name.
If I had any special characters in my Option Display Name (" # &) it would not add any charges associated with that option selection and the coupon code box would also disappear.
E.g my option that I was struggling with was:
What size would you like; 8" x 10", 11" x 14" or 11" x 17"?
It didn't like the "
Each choice had a charge and it wouldn't add that charge to the total.
Hope this helps!
