WooCommerce questions

Hi,

I have a few questions about WooCommerce functionality and maybe extensions that will fulfill this functionality. I have four things that my webshop should be capable of:
– Filter the shop on product sizes(variations) / Brand / Men or Women / Category
– Product size series, so a brand allways has size 1 2 3 4. These should be pickable in the variations part of the product. So actually what I mean is to have product variations per brand that can be easily picked by choosing for that brand.
– Bulk sales. So, I pick articles and the shop will give discount on the selected products. For instance, 1 article 20% discount, 2 articles 30% discount etc.
– Bulk sales, to give discount on the entire shop.

Are these points possible? What points are possible in what way and, when need, with what plugins / extensions?

Thanks in advance.

Kind regards,

Luc
