Ann: Hemp Trial Farm Enters 4th Stage of Development - Flowering, page-54

"Browse the CBD shelf in your local health shop and you’ll find a huge variation of strengths on offer; but a higher CBD content means a higher price. Holland & Barrett sells a 10ml bottle of oil by Jacob Hooy containing 5% CBD for £29.99; Boots stocks 10ml bottles by Dragonfly containing 11.1% CBD for £70. One of the strongest products available is by Love Hemp: a 10ml bottle with 40% CBD, for £259.99. Love Hemp suggests a maximum daily dose of 200mg; while it is thought impossible to overdose on CBD, most producers offer guidance on dosing. I notice that none of the infused products carry warnings about maximum doses, age limits, or driving." (source: The Guardian 14th Sept 2019 UK)

PS: It looks like demand for CBD products may be increasing, which bodes well for price, IMO.
