How to customize the cart error messages

How do I customize the error messages that appear in the cart, such as: The total of your order is too low for all the possible shipping methods -> to say You need to have a minimum order value of $80 in order to qualify for delivery.

This includes other error messages such as the error that says something along the lines of: no delivery methods available for the combined weight of your cart...

And I guess also tying in with this question is how do I Stop the error message all together if I dont want the message to appear at all?

If you don't want any messages, you can hide then with CSS, but that depends on how your template is displaying them...

All the messages, as well as any text in HikaShop can be changed via translation overrides:

And how do I hide it with CSS?

It depends on how your template is displaying them...
Some templates have an option to hide them. For others, a simple display:none; CSS definition fo the class of the element around the messages is enough.
But I can't say anything more precise without looking at that page with firebug.

Otherwise, you could ask your template provider for that... They know their template better than us
