PS 1.5.6.2 Vouchers Error Mystery

[dirsubmit]

Hi everyone,

 

I've had this happen quite a few times now.. the first few times I just thought my buyers are clueless and are making a mistake, but it's happening way too often now!  They say that they are trying to purchase something and they are not able to and are told that they need a voucher.  I personally have not ever come across that and I've tested my site 100's of times in the past three years.  I have no idea how to debug this or replicate it.  Any ideas on how or why this could be happening?

 

They're not trying to use a voucher.. they're just trying to go through the checkout process and they can't because they get a message saying they NEED a voucher?

 

Any help would be appreciated!

 

Thanks
