I bought some "plugs u grow" from GWM

There was a very good offer in Gardener's World Magazine for strawberries. Despite the salutory warning of the poor gent whose crop worked out at £2.63 per fruit. He was magnanimous enough to write in to The Times to warn others - which presumably cost him the additional overhead of a first class stamp - I carried on!
The plugs have seemed to grow before my eyes since I planted them and the containers found amongst the things left behind at the bottom of the garden (and so not costly) are ideal.

I will, however, be counting the strawberries I get and working out the cost of the yield. Thankfully, I got the compost on a buy two get one free. Hence the upfront cost for these strawberry tubs is only £16 including plugs and compost.
