Kefir grains (Newtown RG1)

Any takers for milk kefir grains? I make my own tasty kefir at home and the grains multiply over time. It seems a waste to throw them away! All kept refrigerated and clean. A heaped teaspoon of grains is enough to start if you add 250ml of milk. Look up methods online! Need collecting this evening after 6pm please, or Wednesday evening.
