please See diagram below, but I want to have a solution to having a checkout subtotal that is based on quantity bands. So if I was selling downloadable images and they browsed my store what has 1000+ images. the pricing structure will be any quantity up to 10 (Qty: 1-10) will be a set price (£10). therefore Qty:5 = £10 , Qty:1 = £10 , Qty:10 = £10 , Qty:11 = £20 , Qty:21 = £30
and so on. the main thing to keep in mind is that I want the users to **browse** my online store normally and just add to cart knowing that the total will be worked out.
**Browse** I only highlight this because I've seen other solutions that is based on variation of a product / bundle pack
