Bought this today. Never used before so don't know how good it is. Happy to try it for this price. 4m2 coverage of up to 29 varieties of flowers. Basically you weed soil, shake over and water.
There were quite a lot in a big basket in the sale area. Not sure what full price is. No idea if national. Took a pic but can't get phone app to work so can't upload, sorry.
