Good morning,
I too struggle to believe that this is about transaction fees, even you and I can go online and get card processing at less than 2%. So I wonder if this is a part of a plan to try and reduce the use of credit cards because of chargebacks/Sec. 75 refunds.
My thinking is that either type of refund generally doesn't affect the card issuer (your bank) so the card issuer only loses if the merchant goes bust and unless I am misunderstanding something most of the time if I buy off Amazon that merchant is Amazon, it's Amazon's way of ensuring that they get their commission from third party sellers.
This makes me wonder if Amazon is being bitten by signing up sellers who are causing too many chargebacks /Sec. 75 refunds. The credit card providers are well aware of their obligations under Sec. 75 CCA etc so they may have a policy of
Okay refund as we have to. With debit cards which are only covered by the voluntary agreement there may be more of a reluctance by the card issuer to raise a chargeback as they don't have to and recalling payments does cost the bank a lot of time if it is disputed.
If these third party sellers are actually shipping the product, but are shipping substandard goods that are resulting in claims after a few months it may be Amazon that is having to cover the costs of the chargebacks as the supplier has stopped using the Amazon platform and can't be found.
By creating an "issue" with Visa Credit Cards you can get half of your customer base to switch to debit cards with a possible reduction in chargebacks. It is also interesting that the announcement appears to refer to UK issued Visa cards, ones that are covered by the CCA.
Bye
Ian
