Cheaper balanced strains?

High THC flower has really dropped in price on the medical market over the past few years it’s been fantastic for my budget. But balanced strains have only gotten more expensive and are still limited. They seem to sell out, they must be popular, why haven’t companies imported more? These balanced strains are just so expensive compared to high THC. I’d even take the Tilray warlock, just something under £6 a g please!
