It's not that your point/argument is hard to understand..... it's just the fact you can't see it from the other side that confuses me.
If the seller states insurance is on the buyer as a condition then the buyer needs to either accept or decline..... pretty basic.
Your emt issue would be with the bank just like the failure to delivery issue would be with the delivery service..... difference is with the bank the insurance is not negotiable and is included in the fees and service charges they collect.
Sorry for the derail Wolverine.
