As advised I can answer my own question.
First off my query was about setting maximum price allowed to a cart total, not just product total.
eg.max Total products+shipping+fees=100
Here's the solution:
I found a plugin called min "Min and Max Purchase for WooCommerce".If you set your fee (if you have that implemented) and shipping to static eg. $1 fee and $1 shipping all the time.
You can then set maximum total price of products to [desired maximum price to set - (static shipping cost+ static fee)= total max price to set for products]
From example on top deired maximum [$100 desired maximum total-($1 shipping+$1 fee)=$98 total max price to set for products]
This will only work for your eCommerce website IF your shipping cost are static and not affected by weight of products.
