I just went to the Attitude site & searched "credit card" and this is what I found:
"Because of the ongoing problem with credit card providers such as Mastercard or Visa, who refuse to work with
cannabis seeds related businesses ( and constantly issue enormous fines) we would like to encourage our customers to use alternative payment methods . One of the easiest and most common options is a good old
BANK TRANSFER whichin some countries is also known as a
WIRE TRANSFER. It is basically a transfer of funds from your bank account directly to ours.
If you are a customer who has an online access to your bank account this option will be as simple, effortless and quick as using the debit/credit card. If you do not have an online access to your account you can still go to your bank and make a transfer there.
Just select PAY WITH BANK/WIRE TRANSFER at the checkout and you will receive an email with all the information you need in order to make a wire. When you place an order on our website you will be provided with an order number which needs to be included in the place of Payment reference / Wire transfer description so we can match the payment to the order placed. Once the funds are received your order will get processed as usual.
To encourage you to give this option a try
The Attitude Seed Bank offers you an amazing promo!"
But it looks like if you use a bank transfer you receive a 15% discount.
The cash discount is 20%
