Not showing the VAT is very misleading.
The previous shop allowed to deduct the VAT for EU customers which have a EU VAT number. As I pay less VAT in the country where I live I have to pay more now than before.
The belts show up as two items with a 0€ price. What does this mean?
The payment provider is horrible, when I select credit card the process gets stuck at the end (after I entered all data), no feedback, no email, just nothing
the usability is bad: selections are not made clear and you can click on previous by accident. Then it says "This payment was already processed" and I have to empty the entire shopping cart before I can proceed (which may not even word, see above)
[*] Over all: This is a big leap backwards and I am very frustrated with your new shop.
