Hi, I'm sorry about the problems you've had with the checkout. I can see the orders were being attempted, but in this case, the bank was declining them. We do not see all the reasons for a decline, and they do not share this information with us. We do also offer paypal checkout - you can use this as a guest without a paypal account: they have different links to banks and different security checks, and sometimes a transaction will go through on Paypal, or you can select pay by bank transfer.
We can accept a direct bank transfer or a cheque (after it has cleared).
In some cases the decline will be because the billing address entered isn't matching exactly what the bank has on their system (this wasn't the case this week) - we often see this with businesses - but we do not see the address your bank has for your billing address so we cannot see whether it was close or totally different. This is a check many companies do, but on some sites (especially ones that have a lot of business from Continental Europe), it doesn't necessarily make it obvious to you that the address didn't match.
If we can help any further, please email sales@piggygarden.co.uk
